What is a pound-force foot?

A pound-force foot (lbf*ft) is an imperial unit measuring energy or torque, representing the work done by one pound-force acting over one foot.

How is a newton meter related to the joule?

One newton meter (N*m) is dimensionally equal to one joule, as both represent work or energy transferred by a force acting over a distance.

Can this converter be used for torque values?

Yes, although torque and energy are physically different, this tool can convert values expressed in pound-force foot to newton meter commonly used for torque measurements.
