About Revolutions per minute (RPM)
A rotational-speed unit counting complete 360° turns per minute (1 RPM = 2π/60 rad/s ≈ 0.1047 rad/s = 6°/s). RPM is the dominant everyday rotational-speed unit on tachometers, motor nameplates, and machinery specifications. Reference values: automotive engine idle 700-900 RPM, redline 6,000-9,000 RPM for naturally-aspirated gasoline cars (Honda S2000 F20C 9,000 RPM, Lexus LFA 1LR-GUE 9,500 RPM, F1 V10 engines pre-2014 18,000-20,000 RPM); turbomachinery (steam turbines 3,000 RPM for 50 Hz grid-synchronous / 3,600 RPM for 60 Hz grid; modern aeroderivative gas-turbine 3,600-9,500 RPM depending on shaft); machine tools (typical CNC milling spindle 8,000-24,000 RPM, high-speed machining 30,000-60,000 RPM); hard-disk-drive spindles 5,400 / 7,200 / 10,000 / 15,000 RPM (the last in enterprise SAS drives); ceiling fans 200-300 RPM; washing-machine spin cycles 800-1,600 RPM. Converting RPM to rad/s (multiply by π/30 ≈ 0.1047) is routine for rotor-dynamic analysis and FEA.
About Revolution per second (rev/s)
Rotational speed expressed in full turns per second (1 rev/s = 60 RPM = 2π rad/s ≈ 6.283 rad/s = 360 deg/s). Rev/s is used in specialized contexts where RPM feels too slow or where the per-second timebase matches the calculation's other time units. Common applications: laboratory centrifuges (Beckman Coulter Avanti J-26 max rotor speed ~5,000 RPM = 83 rev/s; Sorvall RC-6+ ~16,000 RPM = 267 rev/s; ultracentrifuges like Beckman Optima MAX 150,000 RPM = 2,500 rev/s for protein and nucleic-acid separation), automotive turbochargers (small passenger-car turbos run 150,000-250,000 RPM = 2,500-4,200 rev/s; truck/marine turbos slower at 30,000-80,000 RPM), high-speed grinding spindles and dental drills (200,000-400,000 RPM = 3,300-6,700 rev/s), and inertial-confinement-fusion target-rotation rigs. 1 rev/s = 60 RPM = 2π rad/s ≈ 6.28 rad/s.

Understanding Revolutions per minute
The Revolutions per minute (symbol: RPM) is a unit of angular velocity. A rotational-speed unit counting complete 360° turns per minute (1 RPM = 2π/60 rad/s ≈ 0.1047 rad/s = 6°/s). RPM is the dominant everyday rotational-speed unit on tachometers, motor nameplates, and machinery specifications.
