Works on the same principle as "60 seconds = 1 minute and 60 minutes = 1 hour (or degree in this case)...
So for example: 2 degrees, 45 Minutes and 20 seconds is worked as follows:
Now, 20 seconds = 0.33 minutes (i.e. 20/60); add to 45 minutes to get 45.33 minutes..
45.33 minutes = 45.33/60 degrees = 0.7555 degrees.
Therefore, final answer is 2 + 0.7555 = 2.7555 degrees....
Hope this helps!!

There are sixty minutes in a degree - so to convert degrees to minutes, you multiply by 60 !
1 degree = 60 minutes 1 minute = 60 seconds 1 degree = 3,600 seconds
I assume you mean you have a latitude of d degrees, m minutes and s seconds that you want as a decimal number. The minutes and seconds are just like time: 1 minute (of arc) = 60 seconds (of arc) 1 degree (of arc) = 60 minutes (of arc) = 60 × 60 seconds (of arc) = 3600 seconds (of arc) → to convert d° m' s" to decimal add: d + m/60 + s/3600 Degrees latitude North are positive, whereas South are negative. eg 52° 6' 15" N is 52 + 6/60 + 15/3600 = 52 + 0.1 + 0.0041666... = 52.1041666...° ≈ 52.1042° eg 47° 12' 40" S is -(47 + 12/60 + 40/3600) = -(47 + 0.2 + 0.0111...) = -47.2111...° ≈ -47.2111°
It is 3600 seconds for you have 60 minutes in every degree so there are 60 seconds in every minute.
