Details In the field of mass, a "slug" is a unit used in the Imperial and United States Customary systems of units. It is a unit of mass that is defined as the mass that is accelerated by 1 foot per second squared (1 ft/s²) when a force of 1 pound-force (1 lbf) is exerted on it. The slug is mainly employed in the field of dynamics and physics, particularly in calculations involving force and acceleration.

1 slug is approximately equal to 32.17405 pounds or 14.5939 kilograms in the International System of Units (SI units).
