About These Units
Revolutions per Hour (RPH)
Revolutions per hour (RPH) measures slow rotational speeds. Clock hour hands move at 1 RPH. Industrial mixers, rotisseries, and some conveyors operate in RPH range. Earth rotates once per 24 hours (approximately 0.042 RPH).
Revolutions per Minute (RPM)
Revolutions per minute (RPM) measures rotational speed. Car engines idle at 600-1000 RPM, redline at 5000-9000 RPM. Hard drives spin at 5400-15000 RPM. Washing machines spin at 400-1800 RPM. One RPM equals 1/60 Hz.
