HP to Joules conversion calculator Calculator Usage Guide

Learn how to use the HP to Joules conversion calculator and its working principles

How to use the calculator

  1. Enter the horsepower (HP) value in the first input field.
  2. Enter the time in seconds for which the horsepower was applied in the second input field.
  3. Click the "Calculate" button to convert HP to joules.
  4. The result will be displayed in the result field.

Working Principle

Horsepower is a unit of power, while joules is a unit of energy. The relationship between them is:

Energy (Joules) = Power (Watts) × Time (seconds)

Since 1 horsepower = 745.7 watts, the formula becomes:

Energy (Joules) = HP × 745.7 × Time (seconds)

Example

If a machine operates at 5 horsepower for 10 seconds, the energy output would be:

Energy = 5 HP × 745.7 W/HP × 10 s = 37,285 joules

Applications

This calculator can be used in engineering, physics, and mechanics to:

  • Calculate energy consumption of mechanical systems
  • Determine work done by engines
  • Compare efficiency of different power sources
