Convert horsepower (550 ft*lbf/s) to terajoule/second

Please provide values below to convert horsepower (550 ft*lbf/s) [hp] to terajoule/second [TJ/s], or Convert terajoule/second to horsepower (550 ft*lbf/s).

1 hp = 7.4570e-10 TJ/s. To convert horsepower (550 ft*lbf/s) 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

Horsepower (550 Ft*lbf/s)

Horsepower (hp) is a unit of power measurement, defined as 550 foot-pounds of work per second (ft·lbf/s).

History/Origin

The horsepower was developed by James Watt in the late 18th century to compare the power of steam engines with draft horses, and it became a standard unit for measuring engine power.

Current Use

Horsepower is still widely used today to rate the power of engines and motors in automotive, aviation, and industrial applications.


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 (550 ft*lbf/s) in terajoule/second?

1 horsepower (550 ft*lbf/s) (hp) = 7.4570e-10 terajoule/second (TJ/s).

How do you convert horsepower (550 ft*lbf/s) to terajoule/second?
