## How to Convert Hertz to Radians Per Second

To convert a hertz measurement to a radian per second measurement, multiply the frequency by the conversion ratio.

Since one hertz is equal to 6.283185 radians per second, you can use this simple formula to convert:

The frequency in radians per second is equal to the hertz multiplied by 6.283185.

**For example,**here's how to convert 5 hertz to radians per second 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 angular frequency ω in radians per second is equal to 2 times pi times the frequency ƒ in hertz.

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

## Hertz

Hertz is formally defined as the frequency equalling one cycle per second.^{[1]}

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}

## 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.^{[2]}
