FAQs
What is a Horsepower-Hour?
A Horsepower-Hour (hp·h) is a unit of energy representing the work done by one horsepower over the course of one hour.
1 horsepower-hour = 2,684,519.54 Joules (J).
What is the relationship between Joules and Horsepower-Hours?
The relationship is defined as:
1 hp·h = 2,684,519.54 J
1 J ≈ 3.725 × 10⁻⁷ hp·h
Why are Horsepower-Hours used instead of Joules?
Horsepower-hours are often used in engineering and automotive industries to describe the energy output of engines or machines over time. It provides a practical unit for large-scale energy use compared to Joules.
