How to Convert Revolutions per Hour to Revolutions per Minute
To convert revolutions per hour to revolutions per minute, multiply the angular velocity by the following conversion ratio: 0.0166667 revolutions per minute/revolution per hour.
Since one revolution per hour is equal to 0.0166667 revolutions per minute, you can use this simple formula to convert:
The angular velocity in revolutions per minute is equal to the angular velocity in revolutions per hour multiplied by 0.0166667.
For example, here's how to convert 5 revolutions per hour to revolutions per minute using the formula above.
How Many Revolutions per Minute Are in a Revolution per Hour?
There are 0.0166667 revolutions per minute in a revolution per hour, which is why we use this value in the formula above.
Our revolution per hour to revolution per minute calculator automatically converts your angular velocity measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

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. [1]
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.
What Is a Revolution per Minute?
A revolution per minute is a unit of angular velocity equal to 0.1047198 radians per second (rad/s), the base unit for angular velocity. One full rotation per minute (2π/60 ≈ 0.10472 rad/s). [2]
The revolution per minute is classified as a standard unit of angular velocity. Revolutions per Minute can be abbreviated as r/min; for example, 1 revolution per minute can be written as 1 r/min.
When working with revolutions per minute (r/min) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, revolutions per minute (r/min) are widely used across standard angular velocity applications within international standard workflows, engineering documentation, and technical data sheets.
When converting angular velocity between revolutions per hour (r/h) and revolutions per minute (r/min), keep full floating-point precision (1 r/h = 0.0166667 r/min; 1 r/min = 60 r/h) during intermediate calculations and round only the final revolution per minute figure to match your instrument tolerance.
