Unit conversion
Angle Converter
Convert angles between degrees, radians, gradians, and turns without wrapping or losing full rotations.
Convert a value
Your values are processed in your browser and are not uploaded to ToolPixels. This tool does not save them.
A full rotation has several names
One turn is 360 degrees, 400 gradians, or 2π radians. Radian conversions use the browser’s floating-point approximation of π.
Negative angles keep their sign. Values above a full turn are not wrapped: 720 degrees converts to 2 turns. Enter decimal degrees, not degrees-minutes-seconds notation.
Example
180 degrees is approximately 3.14159265359 radians.
Precision and input limits
Results use browser floating-point arithmetic and are rounded to your selected number of significant digits, not decimal places. Small or large results may use scientific notation. This is not an arbitrary-precision calculator.
Enter zero or a number with magnitude from 1e-100 to 1e100. Signed values are supported for mathematical conversions. Swap units exchanges the unit choices without changing your input. Editing an input clears the previous result.
