Work out hertz to rpm instantly with clear inputs, formula shown and shareable results.
Converting Hertz to Revolutions per minute is one multiplication: a single Hz is 60 rpm, so the amount is scaled by that factor. Reversing the direction divides by the same factor. The factor is an exact definition rather than a rounded figure, so the result stays precise at any magnitude. A 50 Hz mains supply drives a two-pole synchronous motor at 3000 rpm, which is exactly this conversion.
Hertz → Revolutions per minute
rpm = Hz × 60
Revolutions per minute → Hertz
Hz = rpm ÷ 60
One Hz equals 60 rpm. That value is exact by definition.
Divide by 60 rather than multiplying, or flip the direction selector which does it for you.
