How to Convert Revolutions per Hour to Revolutions per Second

To convert revolutions per hour to revolutions per second, multiply the angular velocity by the following conversion ratio: 0.000277778 revolutions per second/revolution per hour.

Since one revolution per hour is equal to 0.000277778 revolutions per second, you can use this simple formula to convert:

revolutions per second = revolutions per hour × 0.000277778

The angular velocity in revolutions per second is equal to the angular velocity in revolutions per hour multiplied by 0.000277778.

For example, here's how to convert 5 revolutions per hour to revolutions per second using the formula above.

revolutions per second = (5 r/h × 0.000277778) = 0.0013889 r/s

How Many Revolutions per Second Are in a Revolution per Hour?

There are 0.000277778 revolutions per second in a revolution per hour, which is why we use this value in the formula above.

1 r/h = 0.000277778 r/s|1 r/s = 3,600 r/h

Our revolution per hour to revolution per second calculator automatically converts your angular velocity measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

Revolutions per Hour and revolutions per second are both units used to measure angular velocity. Keep reading to learn more about each unit.

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 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). [2]

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.

When converting angular velocity between revolutions per hour (r/h) and revolutions per second (r/s), keep full floating-point precision (1 r/h = 0.000277778 r/s; 1 r/s = 3,600 r/h) during intermediate calculations and round only the final revolution per second figure to match your instrument tolerance.
