About Units

Joules per second: Joules per second (J/s) is a unit of power equivalent to watts in the International System of Units (SI). One joule per second is the rate at which one joule of energy is transferred or converted in one second. It is commonly used in scientific contexts to measure energy transfer rates.

Horsepower: Horsepower (HP) is a unit of measurement of power, originally defined as 550 foot-pounds per second. It is commonly used to measure the power output of engines. For example, the engine of a car might be rated at 300 horsepower. There are different standards for horsepower, including mechanical horsepower, metric horsepower, and electrical horsepower.
