To convert a measurement in hertz to a measurement in radians per second, multiply the frequency by the following conversion ratio: 6.283185 radians per second/hertz.

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

radians per second = hertz × 6.283185

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

For example, here's how to convert 5 hertz to radians per second using the formula above.
radians per second = (5 Hz × 6.283185) = 31.415927 rad/s

How Many Radians per Second Are in a Hertz?

There are 6.283185 radians per second in a hertz, which is why we use this value in the formula above.

1 Hz = 6.283185 rad/s

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

ω = 2πƒ

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.

What Is a Hertz?

One hertz is formally defined as the frequency of 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 in Seconds

What Are Radians per Second?

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

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

In the expressions of units, the slash, or solidus (/), is used to express a change in one or more units relative to a change in one or more other units.[2] For example, rad/s is expressing a change in angle relative to a change in time.
