Fundamental quantities are Force, Length and Time

Unit of Force --- Pound or Pound Wt (the gravitational force exerted by earth
on 1 pound mass with g = 32.17 ft/s/s)
Unit of Length --- Foot
Unit of Time ---- Second

Mass is a derive quantity

Unit of Mass --- Slug

It is the mass in which a pound force produces an acceleration
