How to Convert Radians per Second to Revolutions per Hour
To convert radians per second to revolutions per hour, multiply the angular velocity by the following conversion ratio: 572.9577951 revolutions per hour/radian per second.
Since one radian per second is equal to 572.9577951 revolutions per hour, you can use this simple formula to convert:
The angular velocity in revolutions per hour is equal to the angular velocity in radians per second multiplied by 572.9577951.
For example, here's how to convert 5 radians per second to revolutions per hour using the formula above.
How Many Revolutions per Hour Are in a Radian per Second?
There are 572.9577951 revolutions per hour in a radian per second, which is why we use this value in the formula above.
Our radian per second to revolution per hour calculator automatically converts your angular velocity measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Radians per Second and revolutions per hour are both units used to measure angular velocity. Keep reading to learn more about each unit.
What Is a Radian per Second?
SI unit of angular velocity. It serves as a primary reference unit for measuring angular velocity across scientific and practical applications. [1]
The radian per second is classified as an International System of Units (SI) unit of angular velocity. Radians per Second can be abbreviated as rad/s; for example, 1 radian per second can be written as 1 rad/s.
As the primary coherent reference unit for angular velocity in this category, all other angular velocity units are mathematically anchored to the radian per second (rad/s).
In practice, radians per second (rad/s) are widely used across standard angular velocity applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
What Is a Revolution per Hour?
A revolution per hour is a unit of angular velocity equal to 0.0017453 radians per second (rad/s), the base unit for angular velocity. One full rotation per hour. [2]
The revolution per hour is classified as a standard unit of angular velocity. Revolutions per Hour can be abbreviated as r/h; for example, 1 revolution per hour can be written as 1 r/h.
When working with revolutions per hour (r/h) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, revolutions per hour (r/h) are widely used across fine-tolerance laboratory, analytical, and micro-scale angular velocity measurements within international standard workflows, engineering documentation, and technical data sheets.
When converting angular velocity between radians per second (rad/s) and revolutions per hour (r/h), keep full floating-point precision (1 rad/s = 572.9577951 r/h; 1 r/h = 0.0017453 rad/s) during intermediate calculations and round only the final revolution per hour figure to match your instrument tolerance.
