What is a millijoule?

A millijoule is an SI derived unit of energy equal to one thousandth of a joule, commonly used to measure very small amounts of energy.

What does one foot-pound represent?

One foot-pound represents the work done by a force of one pound-force over a displacement of one foot, equal to about 1.3558 joules.

Why convert from millijoules to foot-pounds?

Conversion helps express small SI energy quantities into imperial units used for mechanical work, ballistics, and torque, facilitating practical applications.
