About Converting Metric ton per Cubic inches to Pounds per Gallon
Metric ton per Cubic inch 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 = metric ton per cubic inches × 509267.825647
This factor comes from each unit's defined relationship to the category's base unit: 1 metric ton per cubic inch equals 61023744.0947 base units, and 1 pound per gallon equals 119.826427317 base units, so dividing one by the other gives the direct metric ton per cubic inch-to-pound per gallon factor of 509267.825647.
Simple example
1 t/in3 × 509267.8256 = 509,267.8256 lb/gal
1 metric ton per cubic inch = 509,267.8256 pounds per gallon.
Real-world example
1,000 t/in3 × 509267.8256 = 509,267,825.6 lb/gal
1,000 metric ton per cubic inches = 509,267,825.6 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.
Uses of the Pound per Gallon today
- US paint and coatings density specifications
- US fuel and petroleum liquid density specs
- Industrial liquid handling and shipping weight calculations
