What does grain/gallon (UK) measure?

It measures density as mass per volume, specifically one avoirdupois grain of mass per imperial (UK) gallon.

When should I use megagram per liter (Mg/L)?

Use megagram per liter when dealing with extremely large densities common in astrophysics, planetary science, or materials physics.

Are conversions between grain/gallon (UK) and Mg/L common?

No, conversions are mostly relevant when translating traditional water hardness units into very large density units used in specialized research.
