I have pounds, I have pounds and then I'm dividing by feet per second square that's the same thing as multiplying by second squared per feet and these units five pounds second squared over feet this is the same thing as a slug, so if I were one hundred and sixty pounds my mass is going to be equal to, my mass is going to be equal to five slugs, so if my mass is seventy kilograms, mass is seventy kilograms, my weight six hundred and eighty six Newtons, so hopefully that clarifies things a little bit.
