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

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

1 hp = 745700 mJ/s. To convert horsepower (550 ft*lbf/s) to millijoule/second, multiply the value by 745700; to go the other way, divide by it (1 mJ/s = 1.34102185866e-06 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 = 745700 mJ/s
  • 1 mJ/s = 1.34102185866e-06 hp
  • 10 hp = 7457000 mJ/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.


Millijoule/second

A millijoule per second (mJ/s) is a unit of power equivalent to one millijoule of energy transferred or converted every second.

History/Origin

The unit derives from the joule, the SI unit of energy, and the second, the SI unit of time. It has been used in contexts requiring small power measurements, especially in scientific and engineering applications, with the millijoule being a submultiple of the joule.

Current Use

Millijoule per second is used to measure small power levels in scientific experiments, electronics, and other fields where precise, small-scale power measurement is necessary, often within the context of energy transfer or consumption rates.
