About Revolutions per Minute and Hertz

Revolutions per minute counts full rotations each minute — 1 rpm equals 1/60 Hz. Engine speeds, hard drives, and washing machine spin cycles are rated in rpm. The hertz is the SI derived unit of frequency — one cycle per second, named after Heinrich Hertz. Sound pitch, mains electricity (50/60 Hz), and display refresh all measure in hertz. One Revolutions per Minute equals 0.01666666667 Hertz (1 rpm = 0.01666666667 Hz). Revolutions per Minute to Hertz conversion comes up most often in engine tachometer readings and in appliance spin speeds, typically when figures need restating for audio pitch and tuning.

Precision and Rounding: Frequency conversions are exact decimal shifts except rpm and rps, which involve the factor 60. Audio and radio work round to convenient figures; clock signals, tuning, and rotating machinery balancing need the unrounded value.

Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).

Worked Example

15 Revolutions per Minute equals 0.25 Hertz.

15 rpm × 0.01666666667 = 0.25 Hz
