How angle converter works
Angles can be measured in several units. Degrees split a full circle into 360 parts; radians express an angle as the ratio of arc length to radius (a full circle is 2ฯ radians); gradians split a circle into 400; and a turn is one full rotation (1). Each converts to the others by a fixed ratio.
This converter passes the value through turns as a common intermediate โ 1 turn = 360 degrees = 2ฯ radians = 400 gradians โ so conversions are exact and round-trip cleanly. It supports degrees, radians, gradians, and turns.
Enter a value, choose the source and target units, and the tool returns the converted angle. Use it for trigonometry homework, geometry, navigation, and any time you need to move between the common angle units.
