What is a foot-pound in energy measurement?

A foot-pound is an imperial unit of energy defined as the work done by a force of one pound-force acting through a displacement of one foot in the force's direction, equivalent to approximately 1.3558 joules.

When should I convert foot-pounds to millijoules?

You should convert foot-pounds to millijoules when precise quantification of small mechanical energy is required, especially for scientific or engineering purposes where SI units are preferred.

Does this conversion consider energy losses or efficiency?

No, this conversion strictly assumes the foot-pound value represents pure mechanical energy and does not account for efficiency or energy loss factors.
