Convert Hertz (Hz) to RPM (rpm)
Convert hertz (Hz) to revolutions per minute (rpm): multiply by 60, since 1 Hz = 60 rpm. One cycle per second is 60 per minute.
Formula
1 Hz = 59.999999 rpm
To convert Hz to rpm, multiply the value by 59.999999.

About Hz to rpm
Hertz counts cycles per second and rpm counts revolutions per minute, so Hz × 60 = rpm — 50 Hz = 3,000 rpm.
This is the reverse of rpm-to-Hz and matters for motors and machinery: a 50 Hz mains-synchronous motor turns at multiples of 3,000 rpm. Engineers convert between Hz, rpm and rad/s depending on whether they are thinking in frequency, rotation or angular velocity.
Frequently Asked Questions
Where does the unit Hz come from?
Hertz is a standard Frequency unit used in specific regions or fields. Its definition has been refined over time to match international measurement standards.
