Instructions and Help about Form 2220 Conversion

Now let's talk about how to convert DMS (degrees, minutes, and seconds) into decimal degrees. Let's think of an hour as being equal to one degree, with 60 minutes in one hour and 3600 seconds in an hour. This will help you remember how to convert DMS to decimal degrees. Let's say we have the value 45 degrees, 28 minutes, and 32 seconds. To convert this to decimal degrees, you need to do the following: 45 + (28/60) + (32/3600). Enter this information into your calculator, and the result should be 45.4756 degrees. Let's try another example. Convert 38 degrees, 41 minutes, and 27 seconds to decimal degrees. Round your answer to four decimal places. The calculation will be 38 + (41/60) + (27/3600). Enter this into your calculator exactly as you see it. The answer is 38.6908 degrees. Let's do one more example. Convert 53 degrees, 18 minutes, and 39 seconds to decimal degrees. The calculation will be 53 + (18/60) + (39/3600). This results in approximately 53.3108 degrees. Now let's learn how to convert decimal degrees back to DMS. Let's say we have the value 38.4256 degrees. To convert this to DMS, take the whole number, which is 38, as the value in degrees. Then, take the decimal value (0.4256) and multiply it by 60. The result is 25.536. Use the whole number (25) as the value in minutes. Finally, take the remaining decimal (0.536) and multiply it by 60. The result is 32.16. Round this down to 32, which will be the value in seconds. Therefore, the answer is 38 degrees, 25 minutes, and 32 seconds. To confirm the answer, enter 38 + (25/60) + (32/3600) into your calculator. The result may not be exact due to rounding, but it should be close. In this case, the result will be 38.4255. If...
