About Converting Ounces per Milliliter to Pounds per Gallon
Ounce per Milliliter 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 = ounces per milliliter × 236.5882365
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per milliliter equals 28349.523125 base units, and 1 pound per gallon equals 119.826427317 base units, so dividing one by the other gives the direct ounce per milliliter-to-pound per gallon factor of 236.5882365.
Simple example
1 oz/mL × 236.5882365 = 236.5882365 lb/gal
1 ounce per milliliter = 236.5882365 pounds per gallon.
Real-world example
1,000 oz/mL × 236.5882365 = 236,588.2365 lb/gal
1,000 ounces per milliliter = 236,588.2365 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
