Frequency converter processes your input in this browser. Inputs and results are excluded from analytics. Recent tools save tool names, visit counts and last-visit times. Saved tools store only their names. Draft saving is optional and stays on this device; delete saved text with the draft controls. Loading text from a URL is optional and contacts that server; its URL and your IP address are visible to the server. An optional “Use in” action keeps a handoff in this tab. The next tool removes it on arrival and ignores it if more than a minute has passed.

How to convert frequency

Rotational frequency counts complete revolutions; angular frequency differs by a factor of 2π.

Multiply by the source unit factor to get the base quantity, then divide by the target factor. The other-units table compares the same value without retyping it.

A worked example

3000 revolutions per minute ÷ 60 = 50 hertz.

Before you use the result

Displayed values are rounded; extra digits do not make your measurement more accurate. Rotational frequency counts complete revolutions; angular frequency differs by a factor of 2π.

revolutions per minute to hertz (Hz): reference values

revolutions per minute	hertz (Hz)
1	0.01666666667
10	0.1666666667
100	1.666666667

Calculated with the same conversion as the tool above.
