Result in Gradians:

1 cir = 400^g

How to Convert Circles to Gradians

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

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

gradians = circles × 400

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

For example, here's how to convert 5 circles to gradians using the formula above.

gradians = (5 cir × 400) = 2,000^g

How Many Gradians Are in a Circle?

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

1 cir = 400^g

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

What Is a Circle?

A circle is the equivalent of 1 revolution around a circle, or 360°.

A circle is sometimes also referred to as a revolution. Circles can be abbreviated as cir; for example, 1 circle can be written as 1 cir.

A circle is more commonly used to describe a round, symmetrical shape with no corners or edges than it is to describe plane angle. The shape is described by its radius and circumference.

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.

Right angles in gradians
Gradians	Degrees
0 grad	0°
100 grad	90°
200 grad	180°
300 grad	270°
400 grad	360°

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 1^g, 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.
