About Converting Pounds per Gallon to Decigrams per Liter
Pound per Gallon and Decigram per Liter 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
decigrams per liter = pounds per gallon × 1198.26427317
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 decigram per liter equals 0.1 base units, so dividing one by the other gives the direct pound per gallon-to-decigram per liter factor of 1198.26427317.
Simple example
1 lb/gal × 1198.264273 = 1,198.264273 dg/L
1 pound per gallon = 1,198.264273 decigrams per liter.
Real-world example
1,000 lb/gal × 1198.264273 = 1,198,264.273 dg/L
1,000 pounds per gallon = 1,198,264.273 decigrams per liter.

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.
