Gradians to Radians Conversion
Enter the angle in gradians below to get the value converted to radians.
How to Convert Gradians to Radians
To convert a gradian measurement to a radian measurement, multiply the angle by the conversion ratio. One gradian is equal to 0.015708 radians, so use this simple formula to convert:
The angle in radians is equal to the gradians multiplied by 0.015708.
Gradians and radians are both units used to measure angle. Keep reading to learn more about each unit of measure.
This unit simplifies the measurements of right angles, as 90° is equal to 100 gradians.
A gradian is sometimes also referred to as a grad, gon, or grade. Gradians can be abbreviated as g, and are also sometimes abbreviated as gr or grd. For example, 1 gradian can be written as 1g, 1 gr, or 1 grd.
A radian is the measurement of angle equal to the start to the end of an arc divided by the radius of the circle or arc. 1 radian is equal to 180/π, or about 57.29578°. There are about 6.28318 radians in a circle.
The radian is the SI derived unit for angle in the metric system. Radians can be abbreviated as rad, and are also sometimes abbreviated as c, r, or R. For example, 1 radian can be written as 1 rad, 1 c, 1 r, or 1 R.
Radians are often expressed using their definition. The formula to find radians is θ = s/r, where the angle in radians θ is equal to the arc length s divided by the radius r. Thus, radians may also be expressed as the formula of arc length over the radius.
