How to Convert Radians per Second to Revolutions per Second
To convert radians per second to revolutions per second, multiply the angular velocity by the following conversion ratio: 0.1591549 revolutions per second/radian per second.
Since one radian per second is equal to 0.1591549 revolutions per second, you can use this simple formula to convert:
The angular velocity in revolutions per second is equal to the angular velocity in radians per second multiplied by 0.1591549.
For example, here's how to convert 10 radians per second to revolutions per second using the formula above.
How Many Revolutions per Second Are in a Radian per Second?
There are 0.1591549 revolutions per second in a radian per second, which is why we use this value in the formula above.
Our radian per second 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.
Radians per Second and revolutions per second 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 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 radians per second (rad/s) and revolutions per second (r/s), keep full floating-point precision (1 rad/s = 0.1591549 r/s; 1 r/s = 6.2831853 rad/s) during intermediate calculations and round only the final revolution per second figure to match your instrument tolerance.
