|---|---|
| Value | Enter value using the definition in the method and example. |
| From | Select the unit or currency in which the entered number is currently expressed. |
| To | Select the unit or currency you need for the answer. |
Understanding your result
The converted value describes the same angle quantity in the selected target unit. Display rounding does not add precision to the original measurement.
Common mistakes
- Confusing the source and target units, or overlooking a prefix or case-sensitive symbol.
- Entering radians when the value is in degrees.
Check your calculation
- Convert to the target unit and then reverse the direction. Within display rounding, you should recover the original value.

How it works
For the displayed direction, 1 rad equals 57.2957795131 °. The engine converts through the shared angle base quantity. Use consistent physical definitions; conversion changes the unit, not the measured quantity. The multiplier is derived from the two centralized unit factors. Keep full precision until the final result; displayed answers use up to 12 significant digits.
Worked example
10 rad converts to 572.957795131 °. For the reverse direction, swap the units and enter 572.957795131 °; the result is approximately 10 rad.
