Yep, that unit of mass is part of the charmingly agricultural U.S. or

For the insufficiently educated: Weight is not the same thing as
mass. They really should have different units. Failure to recognize
that "pounds" refers to weight instead of mass can easily lead to a
calculated answer that's off by a factor of more than 32.

Real users of Mickey mouse units for engineering calculations normally
use "pounds mass" and "pounds force", but I'm sure you know that.  The
slug as a unit of mass makes sense but I have never seen it actually
used.
