About Converting Kilograms per Gallon to Grams per Cubic Centimeter
Kilogram per Gallon and Gram 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. Kilogram per Gallon is most often used for can be used to express liquid density such as fuel or industrial liquids in kilograms per gallon — in practice, kilograms per liter (metric) and pounds per gallon (us customary) are the specific pairings more commonly seen in fuel and liquid-density references.
Formula
grams per cubic centimeter = kilograms per gallon × 0.264172052358
This factor comes from each unit's defined relationship to the category's base unit: 1 kilogram per gallon equals 264.172052358 base units, and 1 gram per cubic centimeter equals 1000 base units, so dividing one by the other gives the direct kilogram per gallon-to-gram per cubic centimeter factor of 0.264172052358.
Simple example
1 kg/gal × 0.2641720524 = 0.2641720524 g/cm3
1 kilogram per gallon = 0.2641720524 grams per cubic centimeter.
Real-world example
1,000 kg/gal × 0.2641720524 = 264.1720524 g/cm3
1,000 kilograms per gallon = 264.1720524 grams per cubic centimeter.

Frequently asked questions
How many grams per cubic centimeter are in 1 kilogram per gallon?
1 kilogram per gallon equals 0.2641720524 grams per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert kilogram per gallon to gram per cubic centimeter?
Multiply the kilogram per gallon value by 0.2641720524. The converter above does this instantly to whatever precision you set.
How do I convert gram per cubic centimeter back to kilogram per gallon?
Use the reverse factor: 1 gram per cubic centimeter equals 3.785411784 kilograms per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a kilogram per gallon?
Kilogram per Gallon (kg/gal) measures density. A mathematically valid way to express liquid density in kilograms per US gallon. It is classified as a mixed metric/US customary density unit.
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.
Is the kilogram per gallon to gram per cubic centimeter conversion exact?
Yes. Both kilogram per gallon and gram per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.2641720524 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.
