How to Convert Gradians to Revolutions

Protractors are often used to measure angle

To convert a gradian measurement to a revolution measurement, multiply the angle by the conversion ratio. One gradian is equal to 0.0025 revolutions, so use this simple formula to convert:

revolutions = gradians × 0.0025

The angle in revolutions is equal to the gradians multiplied by 0.0025.

For example, here's how to convert 5 gradians to revolutions using the formula above.
5g = (5 × 0.0025) = 0.0125 r

Gradians and revolutions are both units used to measure angle. Keep reading to learn more about each unit of measure.

Gradians

A gradian is equal to 1/400 of a revolution or circle, or 9/10°. 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.

Revolutions

A revolution, or turn, is equal to 1 rotation around a circle, or 360°. Revolutions are commonly used to measure the speed of rotation, for example when measuring the revolutions per minute (RPM) of a vehicle's engine.

A revolution is sometimes also referred to as a turn, cycle, or complete rotation. Revolutions can be abbreviated as r, and are also sometimes abbreviated as rev or cyc. For example, 1 revolution can be written as 1 r, 1 rev, or 1 cyc.
