Power to Torque Calculator:

Enter the values of Power in watts and RPM to generate the value of Torque in Newton metres.

Power to Torque Formula:

The power to torque formula converts mechanical power into torque at a given rotational speed, reflecting how much rotational force is generated. It’s essential for analyzing the efficiency and performance of engines and motors.

Torque, T_(N.m) in Newton metre is equated by dividing the product of the value of 60 with power P_(W) in watts by the value of RPM and 2pi.

Torque, T_(N.m) = (P * 60) / (RPM * 2 * pi)

T_(N.m) = Torque in Newton metres,

P = Power in watts

RPM = rotation per minute.

Power to Torque Calculation:

1. An electric motor generates 5000 Watts of power at 1500 RPM. Calculate the torque produced by the motor.

Given: P = 5000 W, RPM = 1500

Torque, T_(N.m) = (P * 60) / (RPM * 2 * pi)

Torque, T_(N.m) = (5000 * 60) / (1500 * 2 * 3.14)

Torque, T_(N.m) = 31.83N.m.

2. A generator produces 38.79N.m torque at a speed of 1800 RPM. Find the power of the generator.

Given: T_(N.m) = 38.79N.m, RPM = 1500

Torque, T_(N.m) = (P * 60) / (RPM * 2 * pi)

38.79 = (P * 60) / (1500 * 2 * 3.14)

P = 7500W.
