7. Foot-pound (energy) - Wikipedia

   en.wikipedia.org/wiki/Foot-pound_(energy)

   Both energy and torque can be expressed as a product of a force vector with a displacement vector (hence pounds and feet); energy is the scalar product of the two, and torque is the vector product. Although calling the torque unit "pound-foot" has been academically suggested, both are still commonly called "foot-pound" in colloquial usage.
