Angular Velocity to Hertz Converter Formula

Understand the math behind the angular velocity to hertz converter. Each variable explained with a worked example.

How It Works

Angular Velocity to Frequency

Formula

f = omega / (2 * pi)

Where omega is angular velocity in radians per second and f is frequency in hertz.

1 full revolution = 2*pi radians = 1 cycle, so dividing by 2*pi converts from radians per second to cycles per second (hertz).

Worked Example

Convert 6.2832 rad/s to Hz.

value = 6.2832
  1. 01f = 6.2832 / (2 x 3.14159)
  2. 02f = 6.2832 / 6.2832 = 1.0000 Hz

Frequently Asked Questions

What is angular velocity?

Angular velocity measures how fast something rotates, expressed in radians per second. One full rotation is 2*pi radians (approximately 6.2832 radians).

How is angular velocity related to RPM?

RPM = angular velocity x 60 / (2*pi). So 1 rad/s equals about 9.549 RPM.
