What does grain/gallon (US) measure?

Grain per U.S. gallon is a density unit indicating mass per volume, commonly used for measuring water hardness and mineral concentrations in water.

When is exagram per liter used?

Exagram per liter is used to represent extremely large densities typical in astrophysics and nuclear physics, such as the density of neutron stars.

Why do converted values to Eg/L appear very small?

Because exagram per liter is an extraordinarily large unit, values converted from grain/gallon (US) result in very small numbers due to the difference in scale.
