Frequently Asked Questions
Degree, Minute, Second (Sexagesimal) Calculations
You can perform calculations using sexagesimal values, and convert values between sexagesimal and decimal.
Performing an addition or subtraction operation between sexagesimal values, or a multiplication or division operation between a sexagesimal value and a decimal value will cause the result to be displayed as a sexagesimal value.
You also can convert between sexagesimal and decimal.
The following is the input format for a sexagesimal value: {degrees} {minutes} {seconds} .
Note
You must always input something for the degrees and minutes, even if they are zero.
Example 1: 2°20’30” + 39’30” = 3°00’00”
- 2203003930
- 3°0’0”
Example 2: Convert 2°15’18” to its decimal equivalent.
- 21518
- 2°15’18”
- (Converts sexagesimal to decimal.)
- 2.255
- (Converts decimal to sexagesimal.)
- 2°15’18”
