Angle converter

Convert degrees, radians, gradians, turns, arcminutes and arcseconds.

Conversion

This tool lets you switch angle measurements for calculations, plans or geometric references.

Result

Approximation

Enter an angle value to convert.

Quick explanation

Enter a positive or negative angle, then choose the source and target units.

Negative angles are accepted because they can represent rotation direction.

Additional information

Why are negative angles allowed?

An angle can indicate rotation direction. Depending on the convention, a negative value can therefore be perfectly valid.

Degrees, radians and turns

A full turn equals 360 degrees, 400 gradians or 2π radians. Arcminutes and arcseconds are used for finer measures.

About approximations

Conversions involving radians rely on π. The rounded display stays readable, while the copied value keeps more digits.

No data transfer

The conversion is calculated locally in the browser.
