What is a grain [gr] used for?

A grain is a traditional unit of mass mostly used for measuring bullet weights, arrow weights, and in some historical pharmaceutical doses.

What does a slug represent in measurement?

A slug is a unit of mass in the Imperial/US customary system defined by the mass accelerated by a force of one pound-force at one foot per second squared.

Why convert grains to slugs?

Conversion from grains to slugs helps translate very small mass measurements into larger mass units needed for dynamics, engineering calculations, and legacy data interpretation.
