## Torque - Power - Angular Velocity - Calculator

Click the chart to get torque, power, r/min values

power_{max}=1200 kW and rpm_{max}=24000 r/min

### Power, P = W (work)/t (time) = Fs/t = Fv

Power, 1 Watt (W) = 1 J/s =1 Nm/s

1 kpm/s = 9.80665 W

1 kcal/h = 1.163 W

1 hp_{m} = 1 metric horsepower = 75 kpm/s = 735.49875 W

1 hp (mechanical horsepower) = 550 lbf*ft/s = 745.7124 W

####
1 kp = 9.80665 N;

1 lb = 0.4536 kg;

1 ft = 0.3048 m;

1 lbf (pound-force) = 9.80665*0.4536 = 4.44829644 N

1 lbf ft (foot-pounds) = 4.44829644 N*0.3048 m=1.355840754912 Nm

Τ = P/ω

Τ = moment or torque

ω = angular velocity (rad/s)

ω= 2πn/60 rads/s
1 revolution = 360^{o} = 2π rad
n = revolutions per minute, (1/min)
lbf ft = pound-force foot
kpm = kilopondmeter
Nm = newtonmeter
kW = kilowatt
