About Converting Pounds per Gallon to Troy ounces per Cubic Millimeter
Pound per Gallon and Troy ounce per Cubic Millimeter 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 cubic millimeter = pounds per gallon × 0.00000385250909689
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 cubic millimeter equals 31103476.8 base units, so dividing one by the other gives the direct pound per gallon-to-troy ounce per cubic millimeter factor of 0.00000385250909689.
Simple example
1 lb/gal × 0.000003852509097 = 0.0000038525 oz t/mm3
1 pound per gallon = 0.0000038525 troy ounces per cubic millimeter.
Real-world example
1,000 lb/gal × 0.000003852509097 = 0.0038525091 oz t/mm3
1,000 pounds per gallon = 0.0038525091 troy ounces per cubic millimeter.

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.
