Rotational Power Calculator
Mechanical rotational power (P) is the product of applied torque (T) and rotational angular velocity (ω). Since mechanical work is torque multiplied by angular displacement (W = T × θ), power also represents the rate of doing work over time (P = W / t).
P = T × ω
- P = mechanical power (kW, hp, W, PS)
- T = shaft torque (N·m, kN·m, lbf·ft, lbf·in)
- ω = rotational speed / angular velocity (RPM, rad/s, Hz)
- W / t = work done per unit time (Joules/sec, Watts)
