Convert horsepower to megajoule/second
Please provide values below to convert horsepower [hp] to megajoule/second [MJ/s], or Convert megajoule/second to horsepower.
1 hp = 0.0007457 MJ/s. To convert horsepower to megajoule/second, multiply the value by 0.0007457; to go the other way, divide by it (1 MJ/s = 1341.02185866 hp). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 hp = 0.0007457 MJ/s
- 1 MJ/s = 1341.02185866 hp
- 10 hp = 0.007457 MJ/s

Horsepower
Horsepower (hp) is a unit of power measurement originally developed to compare the power of engines and motors, representing the rate at which work is done or energy is transferred.
History/Origin
The term was introduced in the late 18th century by James Watt to compare the power of steam engines to draft horses. It became a standard unit in engineering and automotive industries, with its definition evolving over time from mechanical to metric standards.
Current Use
Horsepower is widely used today to rate the power output of engines, motors, and other machinery, especially in automotive, aerospace, and industrial applications. It remains a common unit for expressing engine power in many countries.
Megajoule/second
A megajoule per second (MJ/s) is a unit of power equivalent to one megajoule of energy transferred or converted per second, where 1 megajoule equals 1,000,000 joules.
History/Origin
The megajoule per second has been used in scientific and engineering contexts to quantify large-scale power, especially in fields like physics and energy systems, as a convenient unit for expressing high power levels. It is derived from the SI units of energy (joule) and time (second).
Current Use
Today, MJ/s is primarily used in scientific research, energy production, and engineering to describe high power outputs, such as in power plants, large-scale energy systems, and theoretical calculations involving energy transfer rates.
