Energy per area? A foot-pound is a unit of energy, analogous to a Joule, defined as the amount of energy required to apply one pound of force over a distance of one foot.
I can see a use for such a unit; it's just not one I've ever encountered before.
- jimmyk 16y agoWell, a watt per square meter is a measure of irradiance, so I guess if you integrate that with respect to time you'd get joules per square meter. But I don't know if that gives you anything interesting.
- amalcon 16y agoThe use I had in mind was for the energy cost of producing a material of uniform or irrelevant thickness, such as aluminum foil or photovoltaic cells.
- commandar 16y agoFoot-pounds is very commonly used to measure firearm projectile energy; I've never seen foot-pounds per square inch before, though.
