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

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

1 hp = 7.4570e-16 EJ/s. To convert horsepower (550 ft*lbf/s) to exajoule/second, multiply the value by 7.4570e-16; to go the other way, divide by it (1 EJ/s = 1.3410e+15 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-16 EJ/s
  • 1 EJ/s = 1.3410e+15 hp
  • 10 hp = 7.4570e-15 EJ/s
  • 100 hp = 7.4570e-14 EJ/s

How to Convert Horsepower (550 Ft*lbf/s) 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 (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.


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.

Frequently Asked Questions

What is 1 horsepower (550 ft*lbf/s) in exajoule/second?

1 horsepower (550 ft*lbf/s) (hp) = 7.4570e-16 exajoule/second (EJ/s).

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