What is grain per U.S. gallon used for?

Grain per U.S. gallon is commonly used to measure water hardness and mineral concentration in water treatment and boiler feedwater control.

Why convert from grain/gallon (US) to gigagram/liter?

Converting to gigagram/liter allows the use of extremely large metric density units relevant in astrophysics, high-pressure physics, and theoretical modeling of very dense matter.

Are conversions between these units common for everyday water measurements?

No, such conversions produce very small values and are mainly applicable in advanced scientific research rather than routine water hardness measurements.
