What does grain/gallon (UK) measure?

It measures density as the mass in avoirdupois grains per imperial UK gallon, commonly used for water hardness and dissolved solids.

Where is petagram/liter typically used?

Petagram per liter is used to describe extremely high mass densities in astrophysics and nuclear physics, such as densities in neutron stars.

Is this conversion practical for everyday water quality analysis?

No, because petagram/liter values derived from typical water hardness are extremely small, making this conversion mainly theoretical or comparative.
