Frequently Asked Questions
-
What does pound per US gallon measure?
-
It measures density as the mass in avoirdupois pounds within one US liquid gallon, used mainly in US customary systems.
-
Why convert to grain per UK gallon?
-
This unit is common in the UK for water hardness reporting, boiler feedwater specs, and certain industrial applications.
-
Is the conversion straightforward between these units?
-
No, because the units differ in both mass and volume definitions, requiring accurate conversion factors.
Key Terminology
-
Pound/gallon (US)
-
A density unit indicating mass in avoirdupois pounds per US liquid gallon used primarily in US customary measurements.
-
Grain/gallon (UK)
-
A density unit representing mass in avoirdupois grains per imperial (UK) gallon, used in traditional UK applications like water hardness.
-
Density
-
The measure of mass per unit volume of a substance.
