Convert horsepower (metric) hour to gigajoule
Please provide values below to convert horsepower (metric) hour [hp*h] to gigajoule [GJ], or Convert gigajoule to horsepower (metric) hour.
1 hp*h = 0.0026477955 GJ. To convert horsepower (metric) hour to gigajoule, multiply the value by 0.0026477955; to go the other way, divide by it (1 GJ = 377.672671473 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 = 0.0026477955 GJ
- 1 GJ = 377.672671473 hp*h
- 10 hp*h = 0.026477955 GJ
- 100 hp*h = 0.26477955 GJ
How to Convert Horsepower (Metric) Hour to Gigajoule
1 hp*h = 0.0026477955 GJ
Example: convert 15 hp*h to GJ:
15 hp*h = 15 × 0.0026477955 GJ = 0.0397169325 GJ

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energy in mechanical and engineering contexts, especially in the era of steam and early engines, but has largely been replaced by standard energy units like joules and kilowatt-hours.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.
Gigajoule
A gigajoule (GJ) is a unit of energy equal to one billion joules, used to measure large amounts of energy such as in power generation and fuel consumption.
History/Origin
The gigajoule was introduced as part of the International System of Units (SI) to provide a standard measure for large-scale energy quantities, especially in scientific and industrial contexts, gaining prominence in the 20th century.
Current Use
Gigajoules are commonly used today to quantify energy in fields like energy production, consumption, and engineering, particularly for large-scale systems such as power plants, fuel storage, and energy audits.
