Slug (mass)

The slug is a unit of mass associated with Imperial units. It is a mass that accelerates by 1 ft/s2 when a force of one pound-force (lbF) is exerted on it.

1\,\text{slug} =1\,\frac{\text{lb}_F\cdot\text{s}^2}{\text{ft}} \qquad\Longleftrightarrow\qquad 1\,\text{lb}_F = 1\,\frac{\text{slug}\cdot\text{ft}}{\text{s}^2}

One slug has a mass of 32.17405 lbm or 14.593903 kg based on standard gravity, the international foot, and the avoirdupois pound. At the surface of the Earth, an object with a mass of 1 slug exerts a force of about 32.17 lbF or 143 N.
