Thread: Conversion

I feel dumb for having to ask this, but oh well. This is not homework - I'm studying for a final.

When converting from a Degrees-Minutes-Seconds coordinate system to a Decimal Degrees system, the conversion is simply D+M/60+S/3600. To convert from DD to DMS you leave the integral part of the number, then do, for example, . So you do to get 2625.12, then take , which gives you the minutes, but how do you recover the seconds? I know it's simple but I'm having one of those moments.

1. I don't understand why you multiply by 3600 and then divide by 60 instead of simply multyplying by 60.
2. Then do the same thing again, it's 43M and 0.752*60S

And you asked this question??
