About Hertz and Revolutions per Minute
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. 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. One Hertz equals 60 Revolutions per Minute (1 Hz = 60 rpm). Hertz is used in audio pitch and tuning and in mains power frequency. Revolutions per Minute is used in engine tachometer readings.
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).
