About Converting Pounds per Gallon to Troy ounces per Imperial gallon
Pound per Gallon and Troy ounce per Imperial gallon both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Pound per Gallon is most often used for us paint and coatings density specifications.
Formula
troy ounces per imperial gallon = pounds per gallon × 17.5138530803
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per gallon equals 119.826427317 base units, and 1 troy ounce per imperial gallon equals 6.84180841118 base units, so dividing one by the other gives the direct pound per gallon-to-troy ounce per imperial gallon factor of 17.5138530803.
Simple example
1 lb/gal × 17.51385308 = 17.51385308 oz t/imp gal
1 pound per gallon = 17.51385308 troy ounces per imperial gallon.
Real-world example
1,000 lb/gal × 17.51385308 = 17,513.85308 oz t/imp gal
1,000 pounds per gallon = 17,513.85308 troy ounces per imperial gallon.

Understanding the Pound per Gallon
Pound per Gallon (lb/gal) measures density. The US customary unit for liquid density, based on the US gallon (231 cubic inches). It is classified as a US customary density unit.
Where it's used: United States (paint, fuel, and industrial liquid density specifications)
lb/gal vs. lb/ft³. Both are US customary density units; they're related through the real, fixed relationship between the US gallon and the cubic foot (1 cubic foot ≈ 7.48 US gallons), not a round conversion factor.
