Real-world reference

A motor spinning at 1,000 RPM has an angular velocity of about 104.7 rad/s. Angular velocity in rotational-dynamics equations is conventionally expressed in rad/s. In hertz, that gives you: 1 rad/s = 0.159155 Hz, 10 rad/s = 1.59155 Hz, 100 rad/s = 15.9155 Hz.

Frequently asked questions

How many hertz are in 1 radian per second?
1 radian per second equals 0.159155 hertz.
How do I convert radians per second to hertz?
Multiply the radian per second value by 0.159155. So x rad/s × 0.159155 = the equivalent in Hz.
What is 5 radians per second in hertz?
5 radians per second equals 0.795775 hertz.
What is 10 radians per second in hertz?
10 radians per second equals 1.59155 hertz.
What is 100 radians per second in hertz?
100 radians per second equals 15.9155 hertz.
How do I convert back from hertz to radians per second?
Multiply the hertz value by 6.28319. For example, 1 Hz = 6.28319 rad/s.
Is the radian per second bigger than the hertz?
No. 1 radian per second is smaller than 1 hertz. It takes 6.28319 radians per second to equal 1 hertz.
Are these conversion factors exact?
The factor is derived directly from the SI definitions of radian per second and hertz; the displayed value is rounded for readability, and the browser computes using IEEE 754 double-precision arithmetic.

About the radian per second and the hertz

The radian per second

The radian per second (rad/s) equals 1/(2π) Hz, since one full cycle sweeps out 2π radians. It is the standard unit for angular velocity in physics and control-systems engineering, distinct from RPM's mechanical-engineering convention.

The hertz

The hertz (Hz) is the SI derived unit of frequency, equal to one cycle per second. It is the universal unit for sound pitch, electrical AC frequency, processor clock speed (in multiples), and radio and wireless signal frequencies.
