Convert horsepower (metric) hour to joule
Please provide values below to convert horsepower (metric) hour [hp*h] to joule [J], or Convert joule to horsepower (metric) hour.
1 hp*h = 2647795.5 J. To convert horsepower (metric) hour to joule, multiply the value by 2647795.5; to go the other way, divide by it (1 J = 3.77672671473e-07 hp*h). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 hp*h = 2647795.5 J
- 1 J = 3.77672671473e-07 hp*h
- 10 hp*h = 26477955 J

Horsepower (Metric) Hour
A unit of energy representing the amount of work done by one horsepower over one hour, equivalent to 745.7 joules.
History/Origin
The horsepower hour was historically used to quantify energy in mechanical and engineering contexts, especially in the era of steam and early engines, but has largely been replaced by standard energy units like joules and kilowatt-hours.
Current Use
It is rarely used in modern practice, but may still appear in legacy systems or specific industrial applications to measure energy output or consumption related to horsepower-rated equipment.
Joule
The joule (J) is the SI unit of energy, work, and heat, defined as the work done when a force of one newton acts over a distance of one meter.
History/Origin
The joule was named after James Prescott Joule in 1889 to honor his work in energy and thermodynamics. It was adopted as the SI unit of energy in 1948.
Current Use
The joule is widely used in physics, engineering, and everyday contexts to quantify energy, work, and heat in various applications, including electricity, mechanics, and thermodynamics.
