Which coordinate format is this?

Question

How to split these coordinates to degrees, minutes and seconds?

E0732931.00 and N30 2025.20

Is it 73 degrees, 29 mins and 31 seconds. To convert it to decimal degree, i have to

73+39/60+31/3600?

N30 2025.20 is 30 degs, 20 minutes, 25 seconds? What is the value after the decimal?

2nd i want to ask that is there any coordinate system which uses 100 seconds in a minute, i.e.

decimal degrees = 73+39/60+31/(60*100) ???

Answer 1

Your asumption are correct. Further:

What is the value after the decimal?

the fraction of seconds: so 25.20 seconds

is there any coordinate system which uses 100 seconds in a minute, i.e.

No! There are other systems like DM which uses Degrees and decimal minutes: e.g 23 deg 17.1234 minutes
