Calculation Formula

Torque (Nm) = (Power (kW) × 9549) / Speed (RPM) × Efficiency

Where:
Power (kW): Engine power in kilowatts
Speed (RPM): Rotational speed in revolutions per minute
Efficiency (%): Engine efficiency as a percentage

Torque Output Calculator Usage Guide

Learn how to use the Torque Output Calculator and understand its working principles

How to Use the Calculator

  1. Enter the engine power in kilowatts (kW).
  2. Enter the rotational speed in revolutions per minute (RPM).
  3. Enter the engine efficiency as a percentage (default is 85%).
  4. Click the "Calculate" button to compute the torque output.
  5. The result will be displayed in newton-meters (Nm).

Understanding Torque

Torque is a measure of the rotational force applied to an object. It is calculated as the product of force and the distance from the axis of rotation. In engines, torque is what ultimately produces the force that moves a vehicle.

Calculation Formula

The calculator uses the following formula to calculate torque:

Torque (Nm) = (Power (kW) × 9549) / Speed (RPM) × Efficiency

This formula converts power from kilowatts to torque in newton-meters while accounting for engine efficiency.

Practical Applications

This calculator is useful for:

  • Engine performance analysis
  • Vehicle dynamics calculations
