About Converting Ounces per Gallon to Pound per Cubic inches
Ounce per Gallon and Pound per Cubic inch 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. Ounce per Gallon is most often used for used to express dilution rates on many us pesticide, herbicide, and household cleaning product labels, which commonly specify a number of fluid ounces of concentrate per gallon of water.
Formula
pound per cubic inches = ounces per gallon × 0.000270562770563
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per gallon equals 7.48915170731 base units, and 1 pound per cubic inch equals 27679.9047102 base units, so dividing one by the other gives the direct ounce per gallon-to-pound per cubic inch factor of 0.000270562770563.
Simple example
1 oz/gal × 0.0002705627706 = 0.0002705628 lb/in3
1 ounce per gallon = 0.0002705628 pound per cubic inches.
Real-world example
1,000 oz/gal × 0.0002705627706 = 0.2705627706 lb/in3
1,000 ounces per gallon = 0.2705627706 pound per cubic inches.

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.
