How to Convert Revolutions to Gradians

To convert a measurement in revolutions to a measurement in gradians, multiply the angle by the following conversion ratio: 400 gradians/revolution.

Since one revolution is equal to 400 gradians, you can use this simple formula to convert:

gradians = revolutions × 400

The angle in gradians is equal to the angle in revolutions multiplied by 400.

For example, here's how to convert 5 revolutions to gradians using the formula above.
gradians = (5 r × 400) = 2,000g

How Many Gradians Are in a Revolution?

There are 400 gradians in a revolution, which is why we use this value in the formula above.

1 r = 400g

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

What Is a Revolution?

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.

What Is a Gradian?

A gradian is equal to 1/400 of a revolution or circle, or 9/10°. The grad, or gon, is more precisely defined as π/200, or 1.570796 × 10-2 radians.[1]

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.

In the expressions of units, the slash, or solidus (/), is used to express a change in one or more units relative to a change in one or more other units.
