angular minute to degree
Investigate your GPS options and if you can get the display into decimal degrees like 117.4974 degrees, then you do not need to use this calculator. Test by clicking to calculate the result with the default numbers. The answer should be 117.4974 decimal degrees. i.e. just under 117 and a half degrees. A minute of arc (MOA), arcminute (arcmin) or minute arc is a unit of angular measurement equal to one-sixtieth (1⁄60) of one degree. As one degree is 1⁄360 of a circle, one minute of arc is 1⁄21600 of a circle (or, in radians, π⁄10800). It is used in fields that involve very small angles, such as astronomy, optometry, ophthalmology, optics, navigation, land surveying and marksmanship. Knowing that 1 radian = 57.29578 degrees we can now find the conversion factor for converting back. Dividing both sides of the equation by 57.29578 we get about 0.01745329 radians = 1 degrees. So, the conversion factor to multiply by to convert from degrees to radians is about 0.01745329. Degrees, Minutes, Seconds to Decimal Degrees calculator and vice-versa. Overwrite the default numbers in the bright blue boxes below with the latitude or longitude of your location. Input positive numbers only (e.g. 0 to 360 deg). Decimal degrees. 6 decimal places. The calculation equation is simply: Decimal degrees = whole number of degrees, plus minutes divided by 60, plus seconds divided by 3600. Reverse process: Input decimal degrees and the result is given in deg/min/sec format. Say you want to convert from radians to degrees. Since you can multiply anything by 1 and still retain the original value, but in different units, set it up so that radian will cancel out leaving you with degree. Since: 1 degree = 0.01745329 radians, 1 degree / 0.01745329 radians = 1. We can write the conversion as: 1 radian = 1 radian * (1 degree / 0.01745329 radians) = 57.29578 degrees. And we now have our factor for conversion from radians to degrees since 1 * 57.29578 = 57.29578. Note that there are rounding errors in these values. The angle would be this many degrees, (* means times.): That is, we have 40 full degrees, 20 minutes-each 1/60 of a degree, and 50 seconds-each 1/60 of 1/60 of a degree. Work that out and you will get a decimal number of degrees. It's 40.34722... Going the other way is a bit more difficult. Suppose we start with 40.3472 degrees. Each degree is split up into 60 parts, each part being 1/60 of a degree. These parts are called minutes. Each minute is split up into 60 parts, each part being 1/60 of a minute. These parts are called seconds. The size of an angle could be stated this way: 40 degrees, 20 minutes, 50 seconds. There are symbols that are used when stating angles using degrees, minutes, and seconds. 286.4789 degrees / 57.29578 [degrees / radian] = 5 radians. To convert among any units in the left column, say from A to B, you can multiply by the factor for A to convert A into degrees then divide by the factor for B to convert out of degrees. If you have a GPS receiver display like 117 degrees and 29 minutes and 50.5 seconds then put the numbers in all three blue boxes above in the same manner as shown with the default numbers.
