About Converting Pounds per Gallon to Megagrams per Cubic foot
Pound per Gallon and Megagram 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
megagrams per cubic foot = pounds per gallon × 0.00339310656
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 megagram per cubic foot equals 35314.6667215 base units, so dividing one by the other gives the direct pound per gallon-to-megagram per cubic foot factor of 0.00339310656.
Simple example
1 lb/gal × 0.00339310656 = 0.0033931066 Mg/ft3
1 pound per gallon = 0.0033931066 megagrams per cubic foot.
Real-world example
1,000 lb/gal × 0.00339310656 = 3.39310656 Mg/ft3
1,000 pounds per gallon = 3.39310656 megagrams 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.
