About Converting Pound per Cubic inches to Megagrams per Cubic foot
Pound per Cubic inch 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 Cubic inch is most often used for used in machining and materials engineering, particularly for describing the density of metals, where a smaller volume unit than the cubic foot gives a more convenient figure.
Formula
megagrams per cubic foot = pound per cubic inches × 0.78380761536
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cubic inch equals 27679.9047102 base units, and 1 megagram per cubic foot equals 35314.6667215 base units, so dividing one by the other gives the direct pound per cubic inch-to-megagram per cubic foot factor of 0.78380761536.
Simple example
1 lb/in3 × 0.7838076154 = 0.7838076154 Mg/ft3
1 pound per cubic inch = 0.7838076154 megagrams per cubic foot.
Real-world example
1,000 lb/in3 × 0.7838076154 = 783.8076154 Mg/ft3
1,000 pound per cubic inches = 783.8076154 megagrams per cubic foot.

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.
