What are Millijoule and Horsepower-hour

Definition of Millijoule

A millijoule (mJ) is a unit of energy in the International System of Units (SI), equivalent to one-thousandth of a joule. It's a small energy unit that can be used to describe the amount of work done by a force of one newton moving an object through a distance of one meter. It's commonly used in scientific contexts, particularly in physics and engineering, to measure the energy of small particles or in applications where fine energy measurements are required.

Definition of Horsepower-hour

A horsepower-hour (hp·h) is a unit of energy that represents the work done by a power of one horsepower operating for one hour. Since horsepower is a measure of power, or the rate at which work is performed, a horsepower-hour is thus a unit that combines both power and time, providing a measure of the total energy expended over that period. It's predominantly used in the automotive and machinery industries to estimate the energy consumption or output of engines and motors.
