About Converting Grams per Cubic Centimeter to Grams per Gallon
Gram per Cubic Centimeter and Gram per Gallon 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. Gram per Cubic Centimeter is most often used for material identification in chemistry and geology (mineral density tables).
Formula
grams per gallon = grams per cubic centimeter × 3785.411784
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per cubic centimeter equals 1000 base units, and 1 gram per gallon equals 0.264172052358 base units, so dividing one by the other gives the direct gram per cubic centimeter-to-gram per gallon factor of 3785.411784.
Simple example
1 g/cm3 × 3785.411784 = 3,785.411784 g/gal
1 gram per cubic centimeter = 3,785.411784 grams per gallon.
Real-world example
1,000 g/cm3 × 3785.411784 = 3,785,411.784 g/gal
1,000 grams per cubic centimeter = 3,785,411.784 grams per gallon.

What is a gram per cubic centimeter?
Gram per Cubic Centimeter (g/cm3) measures density. Numerically identical to kilograms per liter, since one cubic centimeter equals one milliliter — this is the form most commonly used in chemistry and materials-science textbooks. It is classified as a metric derived density unit.
What is a gram per gallon?
Gram per Gallon (g/gal) is a unit of density.
Is the gram per cubic centimeter to gram per gallon conversion exact?
Yes. Both gram per cubic centimeter and gram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 3785.411784 used above is exact to as many digits as you choose to display.
Where is the gram per cubic centimeter still used today?
Standard density unit in chemistry and materials science worldwide
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.
