About Hertz To RPM Calculator

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.

Formulas

Hertz → Revolutions per minute

rpm = Hz × 60

Revolutions per minute → Hertz

Hz = rpm ÷ 60

Worked example

Assumptions and limits

  • The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 8 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How many rpm are in one Hz?

One Hz equals 60 rpm. That value is exact by definition.

How do I go from Revolutions per minute back to Hertz?

Divide by 60 rather than multiplying, or flip the direction selector which does it for you.
