Convert horsepower to terajoule/second
Please provide values below to convert horsepower [hp] to terajoule/second [TJ/s], or Convert terajoule/second to horsepower.
1 hp = 7.4570e-10 TJ/s. To convert horsepower to terajoule/second, multiply the value by 7.4570e-10; to go the other way, divide by it (1 TJ/s = 1341021858.66 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 = 7.4570e-10 TJ/s
- 1 TJ/s = 1341021858.66 hp
- 10 hp = 7.457e-09 TJ/s
- 100 hp = 7.457e-08 TJ/s
How to Convert Horsepower to Terajoule/second
1 hp = 7.457e-10 TJ/s
Example: convert 15 hp to TJ/s:
15 hp = 15 × 7.457e-10 TJ/s = 1.11855e-08 TJ/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.
Terajoule/second
A terajoule per second (TJ/s) is a unit of power equivalent to one trillion joules of energy transferred or converted per second.
History/Origin
The terajoule per second is derived from the SI units of energy (joule) and time (second), with 'tera' indicating a factor of 10^12. It is used in scientific and engineering contexts to measure very high power levels, especially in fields like astrophysics and energy production.
Current Use
TJ/s is used to quantify extremely high power outputs, such as in large-scale energy systems, astrophysical phenomena, and nuclear reactions, where conventional units like watts are insufficient to express the magnitude.
Frequently Asked Questions
What is 1 horsepower in terajoule/second?
1 horsepower (hp) = 7.4570e-10 terajoule/second (TJ/s).
How do you convert horsepower to terajoule/second?
Multiply the horsepower value by 7.4570e-10. For example, 25 hp × 7.4570e-10 = 1.86425e-08 TJ/s.
What is 10 horsepower in terajoule/second?
10 hp = 7.457e-09 TJ/s.
Which unit is larger, the horsepower or the terajoule/second?
The terajoule/second is the larger unit: 1 hp equals only 7.4570e-10 TJ/s.
