About Converting Pounds per Gallon to Decagrams per Cubic foot
Pound per Gallon and Decagram per Cubic foot 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
decagrams per cubic foot = pounds per gallon × 339.310656
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 decagram per cubic foot equals 0.353146667215 base units, so dividing one by the other gives the direct pound per gallon-to-decagram per cubic foot factor of 339.310656.
Simple example
1 lb/gal × 339.310656 = 339.310656 dag/ft3
1 pound per gallon = 339.310656 decagrams per cubic foot.
Real-world example
1,000 lb/gal × 339.310656 = 339,310.656 dag/ft3
1,000 pounds per gallon = 339,310.656 decagrams per cubic foot.

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
