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.

Snails and slugs share a common genetic bodily structure but are classed as two significant species; a slug is not a snail without a shell, as is often misidentified.
