It is used primarily in the United States and countries employing the imperial system to measure body weight, food products, and industrial materials [nist-si-guide]. The pound is subdivided into 16 ounces. The pound traces back to Roman libra units, evolving through medieval English measures. The international avoirdupois pound was standardized in 1959 by the United States, United Kingdom, and other anglophone countries to harmonize measurements [nist-si-guide].

It equals exactly 14.593903 kilograms [nist-cuu]. It relates force and acceleration via Newton's second law in Imperial units. The slug originated in the 19th century to simplify force and mass calculations in the British Imperial system. It was formally defined to relate pound-force and foot per second squared units [nist-cuu]. The slug is used primarily in the United States in engineering and physics contexts where Imperial units prevail. It appears in aerospace and mechanical engineering calculations involving forces and masses [nist-cuu].
