 Current Topic:Has anybody heard of a unit called snail? Sorry Ninjatron, but Ogata was correct.  Here is the flaw in your math.   You wrote [lb-sec^2/ft][ft/(12*in)] = lb-sec^2/in   (NO!) This should read [lb-sec^2/ft][ft/(12*in)] = (1/12) (lb-sec^2/ft) (ft/in) = (1/12) [lb-sec^2/in] Thus, 1 slug = 1/12 snail, or 1 snail = 12 slugs as Ogata said. Physically... 1 lbf accelerates 1 snail at 1 in/s^2 1  lbf = (1 snail) (1 in/s^2)  => snail has units lbf s^2/in   1 lbf accelerates 1 sliug at 1 ft/s^2 1  lbf = (1 slug) (1 ft/s^2)  => slug has units lbf s^2/ft So 1 lbf imparts a larger acceleration on 1 slug than on 1 snail.  Thus, slugs are smaller than snails, NOIT the other way around. Hope this helps.  EMA
