What a fucking idiot!

If you knew anything about elementary physics, torque is equal to the
cross product of radial position and force: T = r X F.

In quotidian applications, this equation reduces to T = (lever arm)*(force).

In SI units, force is Newtons and the lever arm, or moment arm, is
meters.  Hence, Torque = N * m.

In the antiquated English units, Torque = feet * lbf (foot-pounds).

Here, we must distinguish "pounds of force," lbf, and "pounds of mass,"
lb.

The proper way to express torque in the English system is lbf-ft,
but the English-derived idiots, including you, usually employ ft-lbf.

I prefer SI units but it will require the English-derived idiots
centuries to adapt.

Fortunately, GNU Units doesn't care:

You have: N m
You want: lbf ft
