# Torque To Power Calculator

## Introduction

In engineering and mechanics, understanding the relationship between torque and power is crucial for designing and analyzing various systems, from automotive engines to industrial machinery. This article will guide you through using a torque to power calculator, explain the formula behind the calculation, provide an example, and answer some frequently asked questions.

## How to Use the Torque to Power Calculator

Using the torque to power calculator is straightforward. Follow these steps:

- Enter the torque value in Newton-meters (Nm).
- Enter the rotational speed in revolutions per minute (RPM).
- Click the “Calculate” button to see the power output in kilowatts (kW).

## Formula

The formula to convert torque (T) and rotational speed (N) to power (P) is:

Where:

- P is the power in kilowatts.
- T is the torque in Newton-meters.
- N is the rotational speed in revolutions per minute.
- The constant 9.5488 converts RPM to radians per second and accounts for the conversion factor between watts and kilowatts.

## Example Solve

Let’s solve an example using the above formula. Suppose you have a torque of 500 Nm and a rotational speed of 3000 RPM. Plugging these values into the formula:

Thus, the power output is approximately 157.08 kW.
