  1. 1 Hz = 6.28318530718 rad/s
  2. 1 × 6.28318530718 = 6.28318530718 rad/s

How to convert hertz to radians per second

1 Hz = 6.28318530718 rad/s, so multiply by 6.28318530718 to go from hertz (cycles per second) to radians per second. Going the other way, 1 rad/s = 0.159154943092 Hz.

rad/s = Hz × 6.28318530718
Hz = rad/s × 0.159154943092

Worked example:

1 Hz = 6.28318530718 rad/s
5 × 6.28318530718 = 31.4159265359 rad/s

About the units

Hertz (Hz)
Hertz (cycles per second), a metric unit. Definition: BIPM SI Brochure, 9th edition (SI units, prefixes and units accepted for use with the SI).
Radians per Second (rad/s)
Radians per second, a metric unit. Involves π, which no fraction equals exactly; this converter uses π to 50 significant digits, far beyond the 12 digits shown. Definition: BIPM SI Brochure, 9th edition (SI units, prefixes and units accepted for use with the SI).
