Revolutions per minute (rpm) to Hertz (rpm to Hz)

Convert revolutions per minute (rpm) to hertz: 1 rpm = 0.0166667 Hz. Exact conversion factor, formula, 22-row table and worked examples, with JSON API and MCP access.

Formula

1 rpm = 0.0166667 Hz

hertz = revolutions per minute (rpm) × 0.01666666667 — reverse: revolutions per minute (rpm) = hertz × 60

The factor is derived from the SI definitions of both units (base unit: Hz) as listed in NIST SP 811; results on this page are shown to 6 significant figures, the API returns up to 12.

FAQ

How many hertz are in one rpm?

1 rpm = 0.0166667 Hz. The factor comes from the SI definitions of both units (NIST SP 811 / BIPM), so it is exact or correct to at least 10 significant figures.

What is the formula to convert revolutions per minute (rpm) to hertz?

Multiply the value in revolutions per minute (rpm) by 0.01666666667: hertz = revolutions per minute (rpm) × 0.01666666667. For example, 5 rpm = 0.0833333 Hz.

How do I convert hertz back to revolutions per minute (rpm)?

Multiply by the inverse factor 60 (revolutions per minute (rpm) = hertz × 60), or use the hertz-to-revolutions per minute (rpm) page.
