How to Convert Horsepower to Joules
Basic Conversion Formula
Understanding the Relationship
Since 1 hp = 745.7 W, the energy in Joules depends on the time duration (in seconds).
1 hp = 745.7 Joules/second
To calculate total energy in Joules, multiply horsepower by the time in seconds:
This formula shows that the energy produced or consumed in joules is directly proportional to the horsepower and the duration of time the power is applied.
Practical Examples
Examples:
- Converting 1 horsepower to joules: J = 1 hp × 2,685,000 ≈ 2,685,000 J
- Converting 5 horsepower to joules: J = 5 hp × 2,685,000 ≈ 13,425,000 J
- Converting 10 horsepower to joules: J = 10 hp × 2,685,000 ≈ 26,850,000 J
Explanation of Terms
hp (Horsepower)
A unit of power that is commonly used to measure the output of engines and motors. One horsepower is equivalent to approximately 746 watts.

FAQs
What is a Joule (J)?
A Joule is the SI unit of energy. It is defined as the energy transferred when 1 watt of power is applied for 1 second.
1 Watt = 1 Joule/second.
What is the relationship between Horsepower and Joules?
Since 1 hp = 745.7 W, the energy in Joules depends on the time duration (in seconds).
1 hp = 745.7 Joules/second
To calculate total energy in Joules, multiply horsepower by the time in seconds:
Energy (J) = Power (hp) × 745.7 × Time (seconds)
How do I convert Horsepower to Joules per second?
Horsepower is directly converted to Joules per second (Watts) as:
1 hp = 745.7 J/s.
Are there different types of horsepower?
Yes, the conversion factor depends on the type of horsepower:
Mechanical Horsepower (most common): 1 hp = 745.7 W.
Metric Horsepower: 1 metric hp = 735.5 W.
Ensure you’re using the correct type of horsepower for accurate conversion.
