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

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

1 hp = 0.178226577438 cal(th)/s. To convert horsepower (550 ft*lbf/s) to calorie (th)/second, multiply the value by 0.178226577438; to go the other way, divide by it (1 cal(th)/s = 5.61083545662 hp). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Quick Reference

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.


Calorie (Th)/second

Calorie (th)/second (cal(th)/s) is a unit of power representing the rate at which thermal calories are transferred or converted per second.

History/Origin

The calorie (th), or thermochemical calorie, was historically used to quantify energy in thermodynamics and nutrition. Its use in power measurement, such as cal(th)/s, emerged in scientific contexts to express thermal energy transfer rates before the adoption of the watt as the standard SI unit.

Current Use

Today, cal(th)/s is rarely used in scientific practice, having been largely replaced by watts (W). It may still appear in specialized fields or historical references related to thermal energy transfer rates.


Frequently Asked Questions

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