lbm?

I'm not sure on your units.

pounds (mass), lbm, as opposed to pounds (force), lbf, or lb.

It is necessary to distinguish between mass and force but they are both
measured in pounds in the english system.

The "English" system uses the "stone" as the measurement of mass.
The pound ('lb') is the unit of *FORCE*.

The 'Stone' is a unit of mass, not "The unit of mass"

All the engineering I ever learned in the British (Imperial) system used
pounds.

Metric is 'much simpler' with grams(mass) and newtons(force).

No - the modern Metric system uses the kilogramme as its fundamental unit.
