Why use grain as a unit of measurement?

Grain is a traditional unit for very small masses, commonly applied in ballistics, archery, and older pharmaceutical contexts.

What is the stone (UK) used for?

Stone (UK) is an imperial mass unit used informally primarily to express human body weight and sometimes in sports or agricultural contexts in the UK and Ireland.

Can I use this converter for scientific measurements?

While useful for traditional conversions, the stone (UK) is not an SI unit and may not be suitable for scientific or international standards.
