## How to Convert Radians Per Second to Hertz

To convert a radian per second measurement to a hertz measurement, multiply the frequency by the conversion ratio. One radian per second is equal to 0.159155 hertz, so use this simple formula to convert:

The frequency in hertz is equal to the radians per second multiplied by 0.159155.

**For example,**here's how to convert 5 radians per second to hertz using the formula above.

The following formula can also be used to convert the angular frequency in radians per second to frequency in hertz:

In other words, the frequency ƒ in hertz is equal to the angular frequency ω in radians per second divided by 2 times pi.

Radians per second and hertz are both units used to measure frequency. Keep reading to learn more about each unit of measure.

## Radians Per Second

Radians per second are a measure of angular frequency, or rotational speed, equal to the change in orientation or angle of an object in radians per second.

Radians per second can be abbreviated as *rad/s*; for example, 1 radian per second can be written as 1 rad/s.

In formal expressions, the slash, or solidus (/), is used to separate units used to indicate division in an expression.^{[1]}

## Hertz

Hertz is formally defined as the frequency equalling one cycle per second.^{[2]}

The hertz is the SI derived unit for frequency in the metric system. Hertz can be abbreviated as *Hz*; for example, 1 hertz can be written as 1 Hz.

Frequency in hertz can be expressed using the formula:
Hz = CyclesTime_{s}
