Frequency Converter
Frequency across hertz, kilohertz and revolutions per minute. Hertz and revolutions per minute measure the same thing, so a motor at 3,000 rpm is running at 50 Hz.
Also called: hz to rpm, rpm converter.
Result
60
1 Hertz is 60 Revolutions per minute. The factor is 60, and the inverse is 0.0166666667. The table below gives the same value in every frequency unit at once.

Method and background
How this is calculated
A hertz is one cycle per second, so anything periodic can be expressed in it. Revolutions per minute is the same quantity divided by sixty, which is why mains frequency and motor speed line up so neatly: a two-pole motor on a 50 Hz supply turns at 3,000 rpm, and on 60 Hz at 3,600.
result = value * factor_from / factor_to- k
- Each unit's size in hertz
