About Converting Grains per Gallon to Ounces per Cubic foot
Grain per Gallon and Ounce 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
ounces per cubic foot = grains per gallon × 0.0170983302412
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per gallon equals 0.0171180610453 base units, and 1 ounce per cubic foot equals 1.00115396087 base units, so dividing one by the other gives the direct grain per gallon-to-ounce per cubic foot factor of 0.0170983302412.
Simple example
1 gr/gal × 0.01709833024 = 0.0170983302 oz/ft3
1 grain per gallon = 0.0170983302 ounces per cubic foot.
Real-world example
1,000 gr/gal × 0.01709833024 = 17.09833024 oz/ft3
1,000 grains per gallon = 17.09833024 ounces per cubic foot.

What is a grain per gallon?
Grain per Gallon (gr/gal) is a unit of density.
What is a ounce per cubic foot?
Ounce per Cubic foot (oz/ft3) is a unit of density.
Is the grain per gallon to ounce per cubic foot conversion exact?
Yes. Both grain per gallon and ounce per cubic foot are defined by fixed standards rather than physical artifacts, so the factor of 0.01709833024 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.
