Key Terminology
-
Grain/gallon (UK)
-
A density unit expressing mass as avoirdupois grains per imperial gallon, often used for water hardness measurements in the UK.
-
Pound/gallon (US)
-
A density unit representing mass in avoirdupois pounds per US liquid gallon, used in fuel and industrial measurement contexts.
-
Density
-
A measurement of mass per unit volume, essential for converting between different units of concentration or hardness.
