About Angle units
Angle can be expressed in degrees, radians, gradians or full turns. Radians are the natural unit in mathematics because they relate arc length directly to radius; degrees dominate everywhere else.
How to use this converter
- Type a value into the box and choose the unit it is in.
- Pick the unit you want on the right — the result updates as you type.
- The table underneath shows the same value in every other Angle unit at once, so you rarely need to convert twice.
Use Swap units to reverse the direction. Values may include thousands separators.
Frequently asked questions
How accurate are the results?
Conversions use exact factors where an exact factor exists, and standard published values otherwise. Results are shown to six significant digits, which is more precision than almost any practical measurement warrants.
Is anything sent to a server?
No. The conversion runs entirely in your browser. Nothing you type is uploaded, logged or stored.
Why does the table skip some units?
A unit is left out when the value has no finite equivalent in it — for example a pace of zero, which would mean standing still forever.
Can I convert several units at once?
Yes. The table under the converter shows your value in every unit of this dimension simultaneously, so you can read off whichever you need.
