About Converting Kilograms per Cubic Centimeter to Grams per Gallon
Kilogram 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. Both are mass per volume density units.
Formula
grams per gallon = kilograms per cubic centimeter × 3785411.784
This factor comes from each unit's defined relationship to the category's base unit: 1 kilogram per cubic centimeter equals 1000000 base units, and 1 gram per gallon equals 0.264172052358 base units, so dividing one by the other gives the direct kilogram per cubic centimeter-to-gram per gallon factor of 3785411.784.
Simple example
1 kg/cm3 × 3785411.784 = 3,785,411.784 g/gal
1 kilogram per cubic centimeter = 3,785,411.784 grams per gallon.
Real-world example
1,000 kg/cm3 × 3785411.784 = 3,785,411,784 g/gal
1,000 kilograms per cubic centimeter = 3,785,411,784 grams per gallon.

Frequently asked questions
How many grams per gallon are in 1 kilogram per cubic centimeter?
1 kilogram per cubic centimeter equals 3,785,411.784 grams per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert kilogram per cubic centimeter to gram per gallon?
Multiply the kilogram per cubic centimeter value by 3785411.784. The converter above does this instantly to whatever precision you set.
How do I convert gram per gallon back to kilogram per cubic centimeter?
Use the reverse factor: 1 gram per gallon equals 2.641721e-7 kilograms per cubic centimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a kilogram per cubic centimeter?
Kilogram per Cubic Centimeter (kg/cm3) is a unit of density.
What is a gram per gallon?
Gram per Gallon (g/gal) is a unit of density.
Is the kilogram per cubic centimeter to gram per gallon conversion exact?
Yes. Both kilogram per cubic centimeter and gram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 3785411.784 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.
