The slug is a unit of mass associated with Imperial units and United States customary units. It is a mass that accelerates by 1 ft/s 2 when a force of one pound (lbF) is exerted on it.
The slug is an English and U.S. customary unit of mass. The slug is part of a subset of coherent units known as the gravitational foot-pound-second system, one of several such specialized systems of mechanical units.It is the mass that accelerates by when a force of one pound-force (lbf) is exerted on it. Therefore a slug is about 32.174 05 pounds or 14.593 90 kg.he slug is part of a subset of coherent units known as the gravitational foot-pound-second system, one of several such specialized systems of mechanical units.
