What is a slug in mass units?

A slug is a unit of mass in the Imperial/US customary system defined by the force needed to accelerate it at 1 ft/s² with one pound-force; it equals about 14.5939 kilograms.

Why convert slug to grain?

This conversion helps translate large inertial masses used in engineering into very small units suitable for ballistics, archery, and pharmaceutical mass measurements.

Where is the grain unit commonly used?

The grain is used for bullet and propellant weights in firearms, arrow weights in archery, and historical pharmaceutical dosages.
