Dear Sir, I think you may need new glasses.
You seem confused. You used pound masses.
Even those who measure power as horses
know that the pound is the unit for forces.
Gravity we need on some occasions,
but it shouldn't be in all equations.
Despite what is claimed by ignorant lugs,
it's customary to measure a mass in slugs.
I know I can't think of anything worse,
except, perhaps, the kilogram-force.
Oh, how I hate those loathesome jackasses,
who always express in pound-fucking-masses.
