Formula

Multiply the value in hertz by 60 to get revolutions per minute.
rpm = Hz × 60

Multiply the value in revolutions per minute by 0.016666667 to get hertz.
Hz = rpm × 0.016666667

About the units

Hertz. The hertz is the SI coherent unit of frequency, one cycle per second, and the name was adopted by the General Conference on Weights and Measures in 1960. It is a legal unit throughout the EU and is used for the mains, radio, sound, clock speeds and screen refresh rates. The definition of the second is expressed in hertz: the caesium frequency is exactly 9,192,631,770 hertz. The trap is what may be counted. The hertz is only for periodic phenomena; random events are measured in becquerels.

Revolutions per minute. Revolutions per minute is a rotational frequency: one revolution per minute is exactly one sixtieth of a hertz, because the minute is exactly 60 seconds. It is used for engine speeds, hard drives, spin cycles and machine tools. There is no standard symbol “rpm” – the American NIST writes r/min and EU type-approval papers min⁻¹. The anchor is that 3,000 revolutions per minute is exactly 50 hertz. The trap is angular velocity: in radians per second it is 2π times the rotational frequency.
