Convert horsepower (metric) hour to millijoule
Please provide values below to convert horsepower (metric) hour [hp*h] to millijoule [mJ], or Convert millijoule to horsepower (metric) hour.
1 hp*h = 2647795500 mJ. To convert horsepower (metric) hour to millijoule, multiply the value by 2647795500; to go the other way, divide by it (1 mJ = 3.7767e-10 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 = 2647795500 mJ
- 1 mJ = 3.7767e-10 hp*h
- 10 hp*h = 26477955000 mJ
- 100 hp*h = 264779550000 mJ
How to Convert Horsepower (Metric) Hour to Millijoule
1 hp*h = 2647795500 mJ
Example: convert 15 hp*h to mJ:
15 hp*h = 15 × 2647795500 mJ = 39716932500 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energy in mechanical and engineering contexts, especially in the era of steam and early engines, but has largely been replaced by standard energy units like joules and kilowatt-hours.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.
Millijoule
A millijoule (mJ) is a unit of energy equal to one thousandth of a joule, where 1 joule equals 1 newton meter or 1 kg·m²/s².
History/Origin
The millijoule is derived from the SI base unit joule, with the prefix 'milli' indicating a factor of 10⁻³. It has been used in scientific and engineering contexts to measure small amounts of energy, especially in fields like electronics and biomechanics.
Current Use
The millijoule is commonly used today to quantify small energy quantities in electronics, biomedical applications, and energy measurements where precision at a small scale is required.
