1. Convert to base units
rad/s = input value x input unit factor
Every supported angular velocity unit is stored as a factor relative to radians per second.

Common conversions
Useful angular velocity conversion factors
| Conversion | Factor | Typical use |
|---|---|---|
| rpm to rad/s | rad/s = rpm x 2 pi / 60 | Motor and shaft speed |
| rad/s to rpm | rpm = rad/s x 60 / 2 pi | Drive and gearbox calculations |
| Hz to rpm | rpm = Hz x 60 | Rotational frequency |
| rev/s to rad/s | rad/s = rev/s x 2 pi | Dynamics |
| deg/s to rad/s | rad/s = deg/s x pi / 180 | Controls and simulation |
| rpm to Hz | Hz = rpm / 60 | Frequency checks |
How it works
Angular Velocity conversion method
2. Convert to target units
target value = base value / target unit factor
The selected result and table values are calculated from the same base value.
3. Check precision
rounding depends on scale
Very small and very large values use compact scientific notation to stay readable.
FAQ
Angular Velocity converter questions
How do you convert rpm to rad/s?
Multiply rpm by 2 pi / 60 to convert to radians per second.
How do you convert rad/s to rpm?
Multiply rad/s by 60 / 2 pi to convert to rpm.
Is hertz the same as revolutions per second?
For rotational speed, 1 Hz corresponds to 1 revolution per second.
