How to Convert Revolutions per Minute to Revolutions per Hour
To convert revolutions per minute to revolutions per hour, multiply the angular velocity by the following conversion ratio: 60 revolutions per hour/revolution per minute.
Since one revolution per minute is equal to 60 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 revolutions per minute multiplied by 60.
For example, here's how to convert 5 revolutions per minute to revolutions per hour using the formula above.
How Many Revolutions per Hour Are in a Revolution per Minute?
There are 60 revolutions per hour in a revolution per minute, which is why we use this value in the formula above.
Our revolution per minute 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.
Revolutions per Minute and revolutions per hour are both units used to measure angular velocity. Keep reading to learn more about each unit.
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). [1]
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.
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 revolutions per minute (r/min) and revolutions per hour (r/h), keep full floating-point precision (1 r/min = 60 r/h; 1 r/h = 0.0166667 r/min) during intermediate calculations and round only the final revolution per hour figure to match your instrument tolerance.
