Convert horsepower (metric) hour to kilojoule
Please provide values below to convert horsepower (metric) hour [hp*h] to kilojoule [kJ], or Convert kilojoule to horsepower (metric) hour.
1 hp*h = 2647.7955 kJ. To convert horsepower (metric) hour to kilojoule, multiply the value by 2647.7955; to go the other way, divide by it (1 kJ = 0.000377672671473 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 = 2647.7955 kJ
- 1 kJ = 0.000377672671473 hp*h
- 10 hp*h = 26477.955 kJ
- 100 hp*h = 264779.55 kJ
How to Convert Horsepower (Metric) Hour to Kilojoule

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energy in mechanical and engineering contexts, especially in the era of steam and early engines, but has largely been replaced by standard energy units like joules and kilowatt-hours.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.
Kilojoule
A kilojoule (kJ) is a unit of energy equal to 1,000 joules, used to quantify energy transfer or work done.
History/Origin
The kilojoule was introduced as part of the International System of Units (SI) to provide a convenient scale for measuring energy, especially in fields like nutrition and physics, replacing the joule for larger quantities.
Current Use
The kilojoule is widely used in nutrition to express food energy content, in physics and engineering to measure energy transfer, and in various scientific and industrial applications within the 'Energy' converter category.
