Convert hp to watts

Horsepower (mechanical)

Mechanical horsepower is a power unit equal to 745.6998715823 watts.

Horsepower originated as a practical way to compare engine output and remains familiar in machinery ratings.

hp is used for engines, electric motors, pumps, compressors, fans, vehicles, and mechanical equipment specifications.

Watt

A watt is the SI unit of power equal to one joule per second.

The watt became the standard power unit for electrical, mechanical, and scientific calculations.

W is used for electronics, appliances, motors, power supplies, lighting, engineering calculations, and electrical load ratings.

How to Convert Horsepower (mechanical) to Watt

Mathematically, watt (W) = horsepower (mechanical) (hp) converted with the formula below.

1 hp = 745.699872 W

1 W = 0.001341 hp

Formula: value × 745.699871582

Example: 15 hp = 11,185.498074 W

1. Start with the power value in horsepower.
2. Use the mechanical horsepower definition: 1 hp = 745.6998715823 W.
3. Multiply the horsepower value by 745.6998715823.
4. Report the converted result in watts.

Precision note: This converter uses mechanical horsepower: 1 hp = 745.6998715823 W. Other horsepower definitions can produce slightly different watt values.
