Advice 1: How to convert degrees to minutes

In minutes and seconds, as a rule, measured by geographical or astronomical coordinates. These units are rarely used in mathematics, physics, and applications in solving various problems both theoretical and applied nature. Here more application as the unit of measurement of plane angles have degrees, whole or fractional. How to convert minutes and seconds to degrees we now find out.

It's very simple: 1 degree is divided into 60 shares, which are called "moments". And every minute, in turn, contains 60 "seconds". As you can see, there is a complete analogy with those minutes and seconds, which for us has always been more associated with the time dimension than the angles and coordinates. So comfortable uniformity of dimension, we owe to the inhabitants of Babylon, from which the legacy of modern civilization got all these hours, minutes and seconds. The Babylonians used a sexagesimal system of calculation.
Of course, apart from minutes and seconds are smaller fractions of a degree. Unfortunately, the simplicity of the ancient ends and the modern bureaucracy. It would be logical to divide by 60 a share, or at least on the usual milliseconds, microseconds, etc. But in the SI system, and home Standards this is not recommended, so fractions of a degree, smaller angular seconds should be recalculated in radians. Fortunately, the measurement of such small angles may need only enough of the prepared. We can meet more of the simple tasks.
So, to the measure of the angle specified in format (degrees minutes seconds convert to decimal degrees, should be to the whole number of degrees to add the number of minutes divided by 60 and the number of seconds divided by 3600. For example, the geographic coordinates of a wonderful place in the city of Krasnodar is 45° 2' 32" North latitude and 38° 58' 50" East longitude. If you count it in the usual degree, we obtain 45° + 2/60 + 32/3600 = 45.0421° North latitude and 38 + 58/60 + 50/3600 = 38.9806 East longitude.
It's easy to do in the calculator, but you can also use Internet resources. On the Internet you will be offered a slight movement of the mouse to convert seconds to degrees, radians, revolutions, Yes, even in miles if there is a desire! Here are some links to online converters angular coordinates:

Advice 2: How to convert seconds to hours

How to convert time from one unit of measure to another. For example, to convert seconds into minutes and hours and Vice versa.
How to convert seconds to hours
You will need
  • Calculator
To convert seconds to hours, it is enough to divide number of seconds by 3600 (since one hour has 60 minutes and each minute 60 seconds. For this you can use an ordinary calculator. Even enough that there is almost any cell phone.

However, it should be noted that the number of hours is sure to be a fractional (decimal: x.y hours). Although decimal representation of time (especially time intervals) and more convenient when carrying out intermediate calculations, the final answer, such a representation is used relatively rarely.

Depending on the specific tasks may need to specify time in the form of: x hours y seconds. In this case, it is sufficient to divide evenly the number of seconds by 3600 - the whole part of the division is the number of hours (x) and modulo the number of seconds (y).

If in the end it should be a specific point in time (clock reading), then the solution is likely to present in the form of: x hours, y minutes, z seconds. For this number of seconds will first have to divide evenly into 3600. The resulting quotient will be the number of hours (Kh). The remainder of the division is necessary again to divide evenly into 60. Obtained in this step, the quotient will be the number of minutes (y), and the remainder of dividing the number of seconds (z).

In order to solve the inverse problem, i.e. to convert seconds to hours, all of the above steps needs to be done in reverse order. Accordingly, for the first case, the number of seconds be x.y*3600, for the second - x*3600+y, and for the third - x*3600+y*60+z.

Although the use of the above-described method and should not cause problems with unit calculations, when large volumes of computation (e.g., processing of experimental data), this process can take time and cause errors. In this case it is better to use the appropriate programs.

For example, using MS Excel, once you enter the necessary formulas to obtain ready-made results. The preparation of suitable formulas do not require user programming skills and is available even to schoolchildren. For example, let's make a formula for our case.

Let the initial number of seconds entered in cell A1.

Then, in the first embodiment, the number of hours will be: =A1/3600

In a second embodiment, the number of hours and seconds: =INTEGER(A1/3600) =MOD(A1;3600), respectively.

In the third embodiment, the number of hours, minutes and seconds can be calculate by the following formulas:
