The slug is a unit of mass in the imperial system, primarily used in physics and engineering calculations involving Newton's second law of motion. One slug equals exactly 14.593903 kilograms or approximately 32.174 pounds. The slug is defined as the mass that accelerates at 1 foot per second squared when a force of one pound-force is applied. This makes it particularly useful in engineering mechanics and dynamics calculations when using imperial units. While rarely used in everyday contexts, the slug remains important in aerospace engineering, mechanical engineering education, and technical calculations where imperial units are standard.
One slug equals exactly 14.593903 kilograms. For most calculations, 14.5939 kg is sufficiently precise.
The origin of the name "slug" for this mass unit is uncertain, but it may derive from the idea of a heavy, sluggish mass. The unit was formalized in the early 20th century for engineering calculations.
One slug equals approximately 32.174 pounds-mass. This relationship comes from the definition of the slug in terms of pound-force and acceleration.
Use slugs in physics and engineering calculations involving force, mass, and acceleration (F = ma) when working in imperial units. Slugs are the proper mass unit, while pounds can represent either force or mass.
While many engineers now prefer metric units, slugs are still used in some aerospace and mechanical engineering contexts, particularly in the United States where imperial units remain common.
One slug is defined such that a force of one pound-force will accelerate it at 1 ft/s squared. This incorporates the gravitational acceleration constant (g = 32.174 ft/s squared) into the unit definition.
