How to Convert Revolutions per Second to Revolutions per Hour
To convert revolutions per second to revolutions per hour, multiply the angular velocity by the following conversion ratio: 3,600 revolutions per hour/revolution per second.
Since one revolution per second is equal to 3,600 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 second multiplied by 3,600.
For example, here's how to convert 5 revolutions per second to revolutions per hour using the formula above.
How Many Revolutions per Hour Are in a Revolution per Second?
There are 3,600 revolutions per hour in a revolution per second, which is why we use this value in the formula above.
Our revolution 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.
Revolutions 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 Revolution per Second?
A revolution per second is a unit of angular velocity equal to 6.2831853 radians per second (rad/s), the base unit for angular velocity. One full rotation per second (2π ≈ 6.28319 rad/s). [1]
The revolution per second is classified as a standard unit of angular velocity. Revolutions per Second can be abbreviated as r/s; for example, 1 revolution per second can be written as 1 r/s.
When working with revolutions per second (r/s) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, revolutions per second (r/s) 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 second (r/s) and revolutions per hour (r/h), keep full floating-point precision (1 r/s = 3,600 r/h; 1 r/h = 0.000277778 r/s) during intermediate calculations and round only the final revolution per hour figure to match your instrument tolerance.
