The formula this calculator uses
Result = value x from-factor / to-factor
- value
- Amount you start with
- from
- Size of the source unit in degrees
- to
- Size of the target unit in degrees
How to check the result by hand
- 1
Enter the amount
Type the number you want to convert.
- 2
Pick the source unit
Choose the unit the number is currently in, such as degrees.
- 3
Pick the target unit
Choose the unit you want the answer in, such as radians.
- 4
Multiply by the source factor
The value is expressed in degrees using the source unit's size in degrees.
- 5
Divide by the target factor
Converting from the base degree into the target unit gives the final answer.
