Converting minutes to hours. How to convert minutes to hours and vice versa: examples, methods, interesting points

Let's take a visual look at how to convert minutes to hours and vice versa. First, let’s agree that we will definitely need knowledge of arithmetic. After all, you can’t do without calculations here. If you can’t do them in your head or on a piece of paper, then use a calculator. Below you will find almost all the options for converting minutes to hours.

From ancient times to modern times

Look at the dial. It has 60 divisions, that is, 60 seconds (minutes). Those who are friends with mathematics have long noticed that this science is similar to a magic trick, mysticism, and thus amuses. Ancient people were no more stupid than our contemporaries; on the contrary, they even succeeded in some ways.

What we have today:

Of course, 3600 seconds was obtained by multiplying 60 minutes * 60 seconds. Let's take another look at the dial: for example, the hour hand (short hand) is at 12, and the minute hand (long hand) shows that it is now 20 minutes. That is twenty minutes past twelve. Now let's look at how to convert minutes to hours with this example.

Simple and complex calculations up to 1 hour

Remember the arithmetic in elementary school and 5th grade: there were fractions. What are we getting at? 1 hour = 60 min. And we only have 20 minutes. It may be incorrect to note that only 20/60 hours have passed. But we know that fractions can be reduced. Let's do this:

In total, 1/3 of an hour has passed, or, if we divide, then 0.33.

Let's consider another option: what does a quarter of an hour mean? How to convert minutes to hours the other way around?

1/4 hour = 15 minutes. How did this happen?

15 min./60 min. = 1/4.

How to correctly write 10 minutes in a clock? The solution technique is identical:

10 min./60 min. = 1/6 hour = 0.167 hour. It is clear that such a recording is incorrect, so it is recommended not to translate 10 minutes.

More than an hour

Many of us have seen how, for example, it is written in the annotation for a film that its duration is: 150 minutes. How to convert minutes to hours in this case? Please note that there will be no more fractions. Why? Because in the previous section we were talking about a time that lasted less than 1 hour. But now it’s the other way around. On the one hand, everything will look easy, but in reality it will be more difficult.

So let's go back to 150 minutes. In order not to think for a long time, let's mentally sum up 60 minutes until we get to the cherished 150: 60 minutes. + 60 min. = 120. We need to stop, because if we add another 60 minutes, it will be 180, and our movie is only 150 minutes long. Back to our 120 minutes. Of course it's 2 hours. Now let’s subtract 120 from 150 minutes. You get 30.

It can be done differently. Stop at 120 minutes and mentally catch up with the missing half hour. Here's the result: 150 min. = 2 hours 30 min. = 2.5 hours.

How to get minutes from 1.5 hours? Immediately imagine 1 hour 30 minutes: 60 + 30 = 90 minutes.

Another option: the arithmetic fraction one whole and five tenths, which after transformation has the form: 15/10 = 3/2. Essentially 1.5 hours is 3/2 hours.

Imagine a 3rd grade lesson that involves fractions. There were also color pictures that clearly showed what 5/6 or 1/2 meant.

Why is such complexity required?

Imagine studying the train schedule. As a rule, they write, for example, travel time: 1 hour 5 minutes. Everything seems to be clear. But let's imagine how long it is in minutes? 65 minutes. Other: 2 hours 35 minutes? Let's calculate:

2 hours = 120 minutes, add another 35 minutes. Total: 120 + 35 = 155 min.

So we looked at how to convert minutes to hours and vice versa. In order to be able to quickly calculate, it is advisable to know the basics of mathematics. If you can’t do the math mentally, you should solve the problem on a piece of paper.

We are used to the fact that there are a thousand grams in one kilogram, and a thousand meters in one kilometer. And everyone understands that 1.5 kilometers is 1500 meters, and 1.3 kilograms is 1300 grams. When it comes to hours and minutes, the usual picture collapses, because 1.2 hours is not 1200 minutes, or 120 minutes, or 1 hour 20 minutes. And sometimes it is very necessary to convert minutes into hours, or hours into seconds. Very often, for example, such a need arises when solving problems in physics, when it is necessary to express a speed expressed in kilometers per hour in meters per second. There is nothing complicated here.

How to convert minutes to hours

How many minutes are there in 1 hour? 60. Actually, based on this, it is already possible to solve the problem.

To convert hours to minutes, just multiply the number of hours by 60:

1 hour = 1 * 60 minutes = 60 minutes

3 hours = 3 * 60 minutes = 180 minutes

5.3 hours = 5.3 * 60 minutes = 318 minutes, or = 5 hours + 0.3 hours = 5 hours + 0.3 * 60 minutes = 5 hours 18 minutes

2.14 hours = 2.14 * 60 minutes = 128.4 minutes

From the last example it is clear that this operation works not only for integer values, but also for fractional ones.

If to convert hours to minutes you had to multiply by 60, then to convert minutes to hours you need to divide the number of minutes by 60:

120 minutes = 120 / 60 = 2 hours

45 minutes = 45 / 60 = 0.75 hours

204 minutes = 204 / 60 = 3.4 hours, or = 3 hours 24 minutes

24.6 minutes = 24.6 / 60 = 0.41 hours

If you need to convert a formula that contains other units of measurement, simply replace one quantity with another, following the rules above. The unit of measurement “hour” should be changed to “60 minutes”, and the “minute” should be replaced by “1/60 of an hour”.

If, when converting hours to minutes, you get a fraction, you can continue the conversion and find out how many seconds are a fraction of a minute.

How to convert minutes to seconds

Since there are sixty seconds in one minute, converting one value into another is also not difficult. To convert minutes to seconds, you need to multiply the time expressed in minutes by 60:

1 minute = 1 * 60 seconds = 60 seconds

3 minutes = 3 * 60 seconds = 180 seconds

5.3 minutes = 5.3 * 60 seconds = 318 seconds, or = 5 minutes + 0.3 minutes = 5 minutes + 0.3 * 60 seconds = 5 minutes 18 seconds

This operation applies to both integer and fractional values.

To convert seconds to minutes, you need to divide the number of seconds by 60:

120 seconds = 120 / 60 = 2 minutes

45 seconds = 45 / 60 = 0.75 minutes

204 seconds = 204 / 60 = 3.4 minutes, or = 3 minutes 24 seconds

24.6 seconds = 24.6 / 60 = 0.41 minutes

When converting various formulas, the unit of measurement “minutes” must be replaced by “60 seconds”, and “second” by “1/60 minutes”.

Now, knowing how to convert seconds to minutes, and minutes to hours, you can easily

convert seconds to hours

Since there are 60 seconds in 1 minute, and 60 minutes in one hour, it turns out that there are 60 * 60 = 3600 seconds in one hour. This means that to convert seconds to hours, you need to divide them by 3600:

8640 seconds = 8640 / 3600 = 2.4 hours

Conversely, to convert hours to seconds, you need to multiply by 3600:

1.2 hours = 1.2 * 3600 seconds = 4320 seconds

You can continue the transformation further. There are 24 hours in a day, 7 days in a week, and 365 days in a year (366 in a leap year). Based on the above examples, I think you can easily convert one time unit to another.

More about time

General information. Physical properties of time

Time can be viewed in two ways: as a mathematical system created to aid our understanding of the Universe and the flow of events, or as a measurement, part of the structure of the Universe. In classical mechanics, time does not depend on other variables and the passage of time is constant. Einstein's theory of relativity, on the contrary, states that events that are simultaneous in one frame of reference can occur asynchronously in another if it is in motion relative to the first. This phenomenon is called relativistic time dilation. The above-described difference in time is significant at speeds close to the speed of light, and has been experimentally proven, for example, in the Hafele-Keating experiment. Scientists synchronized five atomic clocks and left one motionless in the laboratory. The remaining watches flew around the Earth twice on passenger planes. Hafele and Keating found that traveling clocks lag behind stationary clocks, as predicted by the theory of relativity. The effect of gravity, as well as increasing speed, slows down time.

Measuring time

Clocks define the current time in units smaller than one day, while calendars are abstract systems that represent longer time intervals such as days, weeks, months and years. The smallest unit of time is the second, one of the seven SI units. The standard of a second is: “9192631770 periods of radiation corresponding to the transition between two hyperfine levels of the ground state of the cesium-133 atom.”

Mechanical watch

Mechanical clocks typically measure the number of cyclic oscillations of events of a given length, such as the oscillation of a pendulum, which swings once per second. A sundial tracks the movement of the Sun across the sky throughout the day and displays the time on a dial using a shadow. Water clocks, widely used in antiquity and the Middle Ages, measure time by pouring water between several vessels, while hourglasses use sand and similar materials.

The Long Now Foundation in San Francisco is developing a 10,000-year clock called the Clock of the Long Now, which is designed to last and remain accurate for ten thousand years. The project is aimed at creating a simple, understandable and easy-to-use and repair design. No precious metals will be used in the construction of the watch. The design currently requires human operation, including winding the watch. Time is kept by a dual system consisting of an imprecise but reliable mechanical pendulum and an unreliable (due to weather) but accurate lens that collects sunlight. At the time of writing (January 2013), a prototype of this watch is being built.

Atomic clock

Currently, atomic clocks are the most accurate time measuring instruments. They are used to ensure accuracy in radio broadcasting, global navigation satellite systems, and worldwide accurate time measurement. In such clocks, the thermal vibrations of atoms are slowed down by irradiating them with laser light of the appropriate frequency to a temperature close to absolute zero. Time is calculated by measuring the frequency of radiation resulting from the transition of electrons between levels, and the frequency of these oscillations depends on the electrostatic forces between the electrons and the nucleus, as well as on the mass of the nucleus. Currently, the most common atomic clocks use atoms of cesium, rubidium, or hydrogen. Cesium-based atomic clocks are the most accurate in long-term use. Their error is less than one second per million years. Hydrogen atomic clocks are about ten times more accurate over shorter periods of time, up to a week.

Other time measuring instruments

Other measuring instruments include chronometers, which measure time with sufficient accuracy for use in navigation. With their help, they determine the geographical position based on the position of the stars and planets. Today, a chronometer is commonly carried on ships as a backup navigational device, and marine professionals know how to use it in navigation. However, global navigation satellite systems are used more often than chronometers and sextants.

UTC

Around the world, Coordinated Universal Time (UTC) is used as universal system time measurements. It is based on the International Atomic Time (TAI) system, which uses the weighted average time of more than 200 atomic clocks around the world to calculate accurate time. Since 2012, TAI has been 35 seconds ahead of UTC because UTC, unlike TAI, uses the average solar day. Since a solar day is slightly longer than 24 hours, coordination seconds are added to UTC to coordinate UTC with a solar day. Sometimes these seconds of coordination cause various problems, especially in areas where computers are used. To prevent such problems from arising, some institutions, such as the server department at Google, use “leap blur” instead of coordination seconds - lengthening a number of seconds by milliseconds so that the sum of these extensions is equal to one second.

UTC is based on atomic clocks, while Greenwich Mean Time (GMT) is based on length sunny day. GMT is less accurate because it depends on the Earth's rotation period, which is not constant. GMT was widely used in the past, but now UTC is used instead.

Calendars

Calendars consist of one or more levels of cycles such as days, weeks, months and years. They are divided into lunar, solar, lunisolar.

Lunar calendars

Lunar calendars are based on the phases of the moon. Each month is one lunar cycle, and the year is 12 months or 354.37 days. The lunar year is shorter than the solar year, and as a result, lunar calendars synchronize with the solar year only once every 33 lunar years. One of these calendars is Islamic. It is used for religious purposes and as the official calendar in Saudi Arabia.

Solar calendars

Solar calendars are based on the movement of the Sun and the seasons. Their frame of reference is the solar or tropical year, which is the time it takes for the Sun to complete one cycle of seasons, such as from winter solstice to winter solstice. A tropical year is 365,242 days. Because of the precession of the Earth's axis, that is, the slow change in the position of the Earth's axis of rotation, the tropical year is about 20 minutes shorter than the time it takes the Earth to orbit the Sun once relative to the fixed stars (the sidereal year). The tropical year gradually becomes shorter by 0.53 seconds every 100 tropical years, so reform will likely be needed in the future to synchronize solar calendars with the tropical year.

The most famous and widely used solar calendar is the Gregorian calendar. It is based on the Julian calendar, which in turn is based on the old Roman calendar. The Julian calendar assumes that a year consists of 365.25 days. In fact, the tropical year is 11 minutes shorter. As a result of this inaccuracy, by 1582 the Julian calendar was 10 days ahead of the tropical year. The Gregorian calendar was used to correct this discrepancy, and gradually it replaced other calendars in many countries. Some places, including the Orthodox Church, still use the Julian calendar. By 2013, the difference between the Julian and Gregorian calendars is 13 days.

To synchronize the 365-day Gregorian year with the 365.2425-day tropical year, the Gregorian calendar adds a leap year of 366 days. This is done every four years, except for years that are divisible by 100 but not divisible by 400. For example, 2000 was a leap year, but 1900 was not.

Lunar-solar calendars

Lunisolar calendars are a combination of lunar and solar calendars. Typically, their month is equal to the lunar phase, and the months alternate between 29 and 30 days, since the approximate average length of a lunar month is 29.53 days. To synchronize the lunisolar calendar with the tropical year, a thirteenth month is added to the lunar calendar year every few years. For example, in the Hebrew calendar, the thirteenth month is added seven times over the course of nineteen years - this is called the 19-year cycle, or the Metonic cycle. The Chinese and Hindu calendars are also examples of lunisolar calendars.

Other calendars

Other types of calendars are based on astronomical phenomena, such as the movement of Venus, or historical events, such as changes in rulers. For example, the Japanese calendar (年号 nengō, literally the name of an era) is used in addition to the Gregorian calendar. The name of the year corresponds to the name of the period, which is also called the emperor's motto, and the year of the reign of the emperor of that period. Upon accession to the throne, the new emperor approves his motto, and the countdown of a new period begins. The emperor's motto later becomes his posthumous name. According to this scheme, 2013 is called Heisei 25, that is, the 25th year of the reign of Emperor Akihito of the Heisei period.
