Below is something I once posted here...
To convert Degrees-Minutes-Seconds (DMS) to decimal degrees (dd.ddddd),
dd.ddddd = D + M/60 + S/3600
To convert decimal degrees (dd.ddddd) to Degree-Minutes-Seconds (DMS),
D = int(dd.ddddd) int = the integer or whole number part (the part in
front of the decimal
M = int((dd.ddddd - D)*60)
S = (dd.ddddd - (D + M/60))*3600
To convert degrees-decimal minutes (Dmm.mmm) to decimal degrees (dd.ddddd),
dd.ddddd = D + mm.mmm/60
To convert decimal degrees (dd.ddddd) to degrees-decimal minutes (Dmm.mmm),
D = int(dd.ddddd)
mm.mmm = (dd.ddddd-D)*60
To convert degrees-decimal minutes (Dmm.mmm) to Degrees-Minutes-Seconds
(DMS),
D = D
M = int(mm.mmm)
S = (mm.mmm-M)*60
To convert Degrees-Minutes-Seconds (DMS) to degrees-decimal minutes
(Dmm.mmm)
D = D
mm.mmm = M+S/60
If you are going to do a calculation that involves trigonometric functions
of latitude or longitude on a caculator, be sure that it is in degree mode
and use decimal degrees. If in radians mode, you need to convert decimal
degrees into radians by multiplying by pi/180 (which is about 0.01745329,
that should be accurate enough) before entering the number into the
calculator.
