What is an erg per second?

An erg per second (erg/s) is a CGS unit of power defined as one erg of energy transferred per second, used mainly in scientific and astrophysical contexts.

What does horsepower (550 ft*lbf/s) measure?

Horsepower (550 ft*lbf/s) is an imperial unit of power representing the rate of doing work or energy transfer, commonly used to rate engines and mechanical equipment.

Why convert from erg/second to horsepower?

Users convert from erg/second to horsepower to relate scientific power values in CGS units to practical mechanical power measures used in automotive and industrial applications.
