Convert horsepower (metric) hour to megajoule
Please provide values below to convert horsepower (metric) hour [hp*h] to megajoule [MJ], or Convert megajoule to horsepower (metric) hour.
1 hp*h = 2.6477955 MJ. To convert horsepower (metric) hour to megajoule, multiply the value by 2.6477955; to go the other way, divide by it (1 MJ = 0.377672671473 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 = 2.6477955 MJ
- 1 MJ = 0.377672671473 hp*h
- 10 hp*h = 26.477955 MJ
- 100 hp*h = 264.77955 MJ
How to Convert Horsepower (Metric) Hour to Megajoule
1 hp*h = 2.6477955 MJ
Example: convert 15 hp*h to MJ:
15 hp*h = 15 × 2.6477955 MJ = 39.7169325 MJ

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energy in mechanical and engineering contexts, especially in the era of steam and early engines, but has largely been replaced by standard energy units like joules and kilowatt-hours.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.
Megajoule
A megajoule (MJ) is a unit of energy equal to one million joules.
History/Origin
The megajoule was introduced as part of the metric system to measure large amounts of energy, especially in scientific and engineering contexts, aligning with the SI units established in the 20th century.
Current Use
The megajoule is used in fields such as physics, engineering, and energy industries to quantify large energy quantities, including in energy production, consumption, and scientific research.
