Watt (W) to Torque (Nm) Conversion Calculator

Watt (W) to Torque (Nm) Calculator:

Enter the power rating in Watts and speed in rpm, then press the calculate button to get torque in Nm and pound-foot (lb-ft).

Enter Power in Watts: W
Enter Speed in RPM: RPM
Result – Torque in Newton-meter: Nm
Result – Torque in Pound foot : lb-ft

Watt (W) to Torque (Nm) Calculation:

Motor Torque T(Nm) in Newton meter (Nm) is equal to 9.554140127times of the electric power P(W) in watts divided by the speed N(rpm) in rpm.

Hence for converting watt to torque,

T(Nm) = 9.554140127*P(W)/ N(rpm)

Nm = 9.554140127* Watt / RPM

Also our Watt to Nm conversion calculator is designed to get the exact value of torque in Foot-pound force unit (lb-ft)

Nm = 0.74 * lb-ft


Calculate the rated torque can be developed by the 22000 Watts, 1490 rpm three-phase motor.

Apply out Watt to torque conversion formula,

T(Nm) = 9.554140127 *22000 / 1490

T(Nm) = 144 Nm.
