The slug is the unit of mass in the US common system of units, where the pound is the unit of force. The pound is therefore the unit of weight since weight is defined as the force of gravity on an object. While the pound force and pound weight are the widely used units for commerce in the United States, their use is strongly discouraged in scientific work. The standard units for most of scientific work are the SI units.
It was phased out of service fully in the mid-1970s, when the US government announced that the M16 was going to be adopted as a standard small arm (previously, it was intended to be used exclusively as a jungle rifle). The M16 effectively replaced the M14 rifle, M1 Garand rifle (in the case of some National Guard units which still fielded it in the 1970s), M1 carbine, and M3 submachinegun (in most roles).

As I remember from grade school back in the 1960's I believe it was called: "Units and Standards" We refer to the U.S. measurement system today as the "Standard Measurement," "US Standard," "English Units," "US Customary Units," and "Imperial Units."
The system of units used in the United States is called the United States customary units or US customary units. This system includes units such as feet, pounds, and gallons.

Force is measured in units of newtons (N) in the International System of Units (SI) or pounds (lb) in the US customary system.
The appropriate units for measuring time in the US system are seconds, minutes, hours, days, weeks, months, and years.
The three systems of units in physics are the International System of Units (SI), the British Imperial System, and the US Customary System. The SI system is the most widely used and accepted system in the scientific community, while the British Imperial and US Customary systems are primarily used in the United Kingdom and the United States, respectively.
