About Converting Pounds per Gallon to Metric tons per Gallon
Pound per Gallon and Metric ton 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. Pound per Gallon is most often used for us paint and coatings density specifications.
Formula
metric tons per gallon = pounds per gallon × 0.00045359237
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 metric ton per gallon equals 264172.052358 base units, so dividing one by the other gives the direct pound per gallon-to-metric ton per gallon factor of 0.00045359237.
Simple example
1 lb/gal × 0.00045359237 = 0.0004535924 t/gal
1 pound per gallon = 0.0004535924 metric tons per gallon.
Real-world example
1,000 lb/gal × 0.00045359237 = 0.45359237 t/gal
1,000 pounds per gallon = 0.45359237 metric tons 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.
Uses of the Pound per Gallon today
