kW to Nm Calculator

Calculate Torque in Nm from kW



Formula

To calculate the Torque (T):

\[ T = \frac{P \times 1000}{2 \pi \times \left( \frac{RPM}{60} \right)} \]

Where:

What is Torque?

Torque is a measure of the force that can cause an object to rotate about an axis. It is a vector quantity, meaning it has both magnitude and direction. Torque is commonly measured in Newton-meters (Nm) in the metric system. In the context of engines and motors, torque measures the rotational force produced by the engine’s crankshaft or motor’s rotor.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ T = \frac{100 \times 1000}{2 \pi \times \left( \frac{3000}{60} \right)} = \frac{100000}{314.16} = 318.31 \text{ Nm} \]

The Torque is 318.31 Nm.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ T = \frac{50 \times 1000}{2 \pi \times \left( \frac{1500}{60} \right)} = \frac{50000}{157.08} = 318.31 \text{ Nm} \]

The Torque is 318.31 Nm.
