How to Convert Gradians to Revolutions
To convert gradians to revolutions, multiply the angle by the following conversion ratio: 0.0025 revolutions/gradian.
Since one gradian is equal to 0.0025 revolutions, you can use this simple formula to convert:
The angle in revolutions is equal to the angle in gradians multiplied by 0.0025.
For example, here's how to convert 5 gradians to revolutions using the formula above.
How Many Revolutions Are in a Gradian?
There are 0.0025 revolutions in a gradian, which is why we use this value in the formula above.
Our gradian to revolution calculator automatically converts your angle measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Gradians and revolutions are both units used to measure angle. Keep reading to learn more about each unit.
What Is a Gradian?
A gradian is a unit of angle equal to 0.9 degrees (°), the base unit for angle. 1/400 of a full circle (0.9°). [1]
The gradian is classified as a metric and SI-compatible unit of angle. Gradians can be abbreviated as grad; for example, 1 gradian can be written as 1 grad.
When working with gradians (grad) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, gradians (grad) are widely used across standard angle applications within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Revolution?
A revolution is a unit of angle equal to 360 degrees (°), the base unit for angle. Complete 360° circle (2π radians). [2]
The revolution is classified as a standard unit of angle. Revolutions can be abbreviated as rev; for example, 1 revolution can be written as 1 rev.
When working with revolutions (rev) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, revolutions (rev) are widely used across standard angle applications within international standard workflows, engineering documentation, and technical data sheets.
When converting angle between gradians (grad) and revolutions (rev), keep full floating-point precision (1 grad = 0.0025 rev; 1 rev = 400 grad) during intermediate calculations and round only the final revolution figure to match your instrument tolerance.
