Convert Revolutions per minute to Degrees per minute

Convert Revolutions per minute (rpm) to Degrees per minute (°/min) instantly and accurately.

Conversion Formula

°/min = rpm × 360

About Revolutions per minute

The revolution per minute (rpm) equals π/30 rad/s ≈ 0.1047 rad/s, the most universally recognised rotational speed unit in mechanical engineering. Common references: car petrol engines idle at 600-900 rpm, redline at 5500-8500 rpm; large marine diesel engines run at 75-120 rpm; electric induction motor synchronous speed = 60f/p rpm (3000 rpm at 50 Hz, 2-pole); hard drives at 5400-15000 rpm; dental turbines up to 400000 rpm; washing machine spin 400-1600 rpm. ISO 6336 and ANSI/AGMA gear standards use rpm throughout. 1 rpm = π/30 rad/s = 6 °/s = 1/60 rps.

About Degrees per minute

The degree per minute (°/min) equals π/10800 rad/s ≈ 2.909 × 10⁻⁴ rad/s. The sidereal tracking rate for astronomical telescopes is 0.25 °/min (15 °/h); modern robotic observatories slew at 100-400 °/min between targets. A clock's hour hand turns at 0.5 °/min; the minute hand at 6 °/min. Industrial drum conveyors for cement kilns rotate at 0.5-5 °/min; automotive power-steering columns during parking manoeuvres rotate at 30-180 °/min. 1 °/min ≈ 2.909 × 10⁻⁴ rad/s = 1/60 rpm.
