A radian per second is a measure of angular velocity. It represents how fast an object rotates or revolves. If an object rotates one radian in one second, its angular velocity is one radian per second.

## Hertz (Hz)

Hertz is the unit of frequency in the International System of Units (SI). It measures how often something happens within a second. In most contexts, it refers to how many cycles a periodic function completes in one second.

### How to calculate hertz from rad/sec

or

1 rad/s = 1/2π Hz = 0.1591549 Hz

Example- Calculate frequency in hertz from angular velocity of 300 rad/s

Ans. f(Hz) = 300rad/s / 2π = 47.75 Hz

## FAQs on Radian/sec to hertz conversion

### Is Hz equal to rad/sec?

No, Hz (hertz) and rad/sec (radians per second) are both units of frequency, but they are not equivalent. Hz measures the number of cycles per second, while rad/sec measures the angular frequency or the rate of change of the phase of a sinusoidal waveform.

### Is hertz equal to 1 sec?

No, hertz represents the number of cycles per second. A frequency of 1 hertz means one cycle occurs every second, but hertz itself is not equal to seconds.

### What is 1 hertz in radians?

1 hertz represents 1 cycle per second, and a full cycle in terms of radians is 2π radians. So, 1 Hz=2π rad/sec.

### How fast is 1 radian per second?

1 radian per second means that in one second, something has moved through an angle of 1 radian. It's a measure of angular speed.

### What units are hertz?

Hertz (Hz) is the unit of frequency in the International System of Units (SI). It is used to represent the number of cycles per second.
