About Converting Megagrams per Gallon to Pounds per Cubic foot
Megagram per Gallon and Pound 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. Both are mass per volume density units.
Formula
pounds per cubic foot = megagrams per gallon × 16491.7224699
This factor comes from each unit's defined relationship to the category's base unit: 1 megagram per gallon equals 264172.052358 base units, and 1 pound per cubic foot equals 16.018463374 base units, so dividing one by the other gives the direct megagram per gallon-to-pound per cubic foot factor of 16491.7224699.
Simple example
1 Mg/gal × 16491.72247 = 16,491.72247 lb/ft3
1 megagram per gallon = 16,491.72247 pounds per cubic foot.
Real-world example
1,000 Mg/gal × 16491.72247 = 16,491,722.47 lb/ft3
1,000 megagrams per gallon = 16,491,722.47 pounds per cubic foot.

What is a megagram per gallon?
Megagram per Gallon (Mg/gal) is a unit of density.
What is a pound per cubic foot?
Pound per Cubic foot (lb/ft3) measures density. The US customary unit for expressing density, commonly used in construction and engineering material specifications. It is classified as a US customary density unit.
Is the megagram per gallon to pound per cubic foot conversion exact?
Yes. Both megagram per gallon and pound per cubic foot are defined by fixed standards rather than physical artifacts, so the factor of 16491.72247 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
