How to Convert Revolutions to Gradians
To convert revolutions to 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:
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.
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.
Our revolution to gradian calculator automatically converts your angle measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Revolutions and gradians are both units used to measure angle. Keep reading to learn more about each unit.
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). [1]
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.
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°). [2]
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.
When converting angle between revolutions (rev) and gradians (grad), keep full floating-point precision (1 rev = 400 grad; 1 grad = 0.0025 rev) during intermediate calculations and round only the final gradian figure to match your instrument tolerance.
