About Converting Pounds per Gallon to Troy ounces per Teaspoon
Pound per Gallon and Troy ounce per Teaspoon 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 teaspoon = pounds per gallon × 0.0189887152778
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 teaspoon equals 6310.40202373 base units, so dividing one by the other gives the direct pound per gallon-to-troy ounce per teaspoon factor of 0.0189887152778.
Simple example
1 lb/gal × 0.01898871528 = 0.0189887153 oz t/tsp
1 pound per gallon = 0.0189887153 troy ounces per teaspoon.
Real-world example
1,000 lb/gal × 0.01898871528 = 18.98871528 oz t/tsp
1,000 pounds per gallon = 18.98871528 troy ounces per teaspoon.

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.
