Current Topic:
Pounds Mass vs. Force
often it is a huge diference between the Physic school room , and the floor shop.

Both have it's onw true , but if you are on a shop floor,  you need to have the units , as G will be the same here or there for practical purpouse.
And nobody can measurre MASS , and on any grocery you have a  scale to weight it , or a simple rule to cubic the piece, or a graduated vessell to know the  hole volumen.

For me using metric units water weigth 1 , aluminiun 2,7 and steell 7.85  of course gr/cm3 or Kg/liter
