About Converting Troy ounces per Gallon to Pounds per Gallon
Troy ounce per Gallon and Pound per 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. Both are mass per volume density units.
Formula
pounds per gallon = troy ounces per gallon × 0.0685714285714
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per gallon equals 8.21666930173 base units, and 1 pound per gallon equals 119.826427317 base units, so dividing one by the other gives the direct troy ounce per gallon-to-pound per gallon factor of 0.0685714285714.
Simple example
1 oz t/gal × 0.06857142857 = 0.0685714286 lb/gal
1 troy ounce per gallon = 0.0685714286 pounds per gallon.
Real-world example
1,000 oz t/gal × 0.06857142857 = 68.57142857 lb/gal
1,000 troy ounces per gallon = 68.57142857 pounds per 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.
