About Converting Grains per Gallon to Ounces per Cubic Centimeter
Grain per Gallon and Ounce per Cubic Centimeter 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 centimeter = grains per gallon × 6.038218e-7
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 centimeter equals 28349.523125 base units, so dividing one by the other gives the direct grain per gallon-to-ounce per cubic centimeter factor of 6.038218e-7.
Simple example
1 gr/gal × 6.038218e-7 = 6.038218e-7 oz/cm3
1 grain per gallon = 6.038218e-7 ounces per cubic centimeter.
Real-world example
1,000 gr/gal × 6.038218e-7 = 0.0006038218 oz/cm3
1,000 grains per gallon = 0.0006038218 ounces per cubic centimeter.

Frequently asked questions
How many ounces per cubic centimeter are in 1 grain per gallon?
1 grain per gallon equals 6.038218e-7 ounces per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert grain per gallon to ounce per cubic centimeter?
Multiply the grain per gallon value by 6.038218e-7. The converter above does this instantly to whatever precision you set.
How do I convert ounce per cubic centimeter back to grain per gallon?
Use the reverse factor: 1 ounce per cubic centimeter equals 1,656,117.656 grains per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per gallon?
Grain per Gallon (gr/gal) is a unit of density.
What is a ounce per cubic centimeter?
Ounce per Cubic Centimeter (oz/cm3) is a unit of density.
Is the grain per gallon to ounce per cubic centimeter conversion exact?
Yes. Both grain per gallon and ounce per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 6.038218e-7 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.
