# Pound-foot (torque)

A **pound-foot** (**lb·ft** or **lb _{f}·ft**) is a unit of torque (a pseudovector). One pound-foot is the torque created by one pound force acting at a perpendicular distance of one foot from a pivot point.

One pound-foot is approximately 1.355818 newton meters.

The name "pound-foot", intended to minimize confusion with the foot-pound as a unit of work, was apparently first proposed by British physicist Arthur Mason Worthington.^{[1]} However, the torque unit is often still referred to as the **foot-pound** (**ft·lb** or **ft·lb _{f}**).
