Convert horsepower to exajoule/second
Please provide values below to convert horsepower [hp] to exajoule/second [EJ/s], or Convert exajoule/second to horsepower.
How to Convert Horsepower to Exajoule/second
1 hp = 7.457e-16 EJ/s
Example: convert 15 hp to EJ/s:
15 hp = 15 × 7.457e-16 EJ/s = 1.11855e-14 EJ/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.
Exajoule/second
An exajoule per second (EJ/s) is a unit of power representing the transfer or conversion of one exajoule of energy every second.
History/Origin
The exajoule (EJ) is a metric unit of energy introduced as part of the International System of Units (SI) to measure large quantities of energy. The concept of power units like EJ/s emerged with the development of large-scale energy measurement, particularly in fields such as astrophysics and energy production, to quantify extremely high power levels.
Current Use
EJ/s is used primarily in theoretical and large-scale energy discussions, such as in astrophysics, planetary science, and global energy consumption analysis, where extremely high power levels are involved.
