Last update: 2026
The Radian Converter supports 14 different angle units. This makes it possible to convert freely between radians [rad] and other internationally common angle units. All angle values are converted in real time and displayed with up to 20 decimal places, ensuring sufficient accuracy.
Conversion of radians
In order to convert radians [rad] into another angle unit, a conversion value or a suitable calculation method is required. Both can be determined using a conversion table. However, the table is relatively large and confusing, making it difficult for inexperienced users to understand. The following tool provides a solution to this problem by allowing conversion values and calculation methods for radians [rad] to be queried directly from the conversion table.

Conversion between radians and milliradians
A quick and precise conversion between radians [rad] and milliradians [mrad] is straightforward and requires only multiplication or division by 1,000. The conversion from radians [rad] to milliradians [mrad] is done by multiplying the value in radians [rad] by 1,000. To reverse the conversion, divide the value in milliradians [mrad] by 1,000 to obtain radians [rad].
- Milliradians [mrad] = radians [rad] * 1,000
- Radians [rad] = milliradians [mrad] ÷ 1,000
Conversion between radians and turns
You can easily convert between radians [rad] and turns [tr] using the formulas provided below. For accurate results, it is important to follow the correct order of mathematical operations.
- Turns [tr] = radians [rad] ÷ π ÷ 2
- Radians [rad] = turns [tr] * π * 2
Conversion between radians and degrees
The fastest and easiest way to convert between degrees [°] and radians [rad] is to use the converter above. Manual conversions are also possible and can be done using the formulas provided below.
- Radians [rad] = degrees [°] * π ÷ 180
- Degrees [°] = radians [rad] * 180 ÷ π
Conversion between radians and revolutions
The two formulas below provide an easy way to convert between radians [rad] and revolutions [r]. To ensure precise conversion results, it is important to follow the correct order of math operations.
- Revolutions [r] = radians [rad] ÷ π ÷ 2
- Radians [rad] = revolutions [r] * π * 2
Conversion between radians and gons
You can easily convert between radians [rad] and gons [gon] using the formulas provided below. For accurate results, it is important to follow the correct order of mathematical operations.
- Gons [gon] = radians [rad] ÷ π * 200
- Radians [rad] = gons [gon] * π ÷ 200
