About Converting Grams per Cubic Centimeter to Kilograms per Gallon
Gram per Cubic Centimeter and Kilogram 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
kilograms per gallon = grams per cubic centimeter × 3.785411784
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 kilogram per gallon equals 264.172052358 base units, so dividing one by the other gives the direct gram per cubic centimeter-to-kilogram per gallon factor of 3.785411784.
Simple example
1 g/cm3 × 3.785411784 = 3.785411784 kg/gal
1 gram per cubic centimeter = 3.785411784 kilograms per gallon.
Real-world example
1,000 g/cm3 × 3.785411784 = 3,785.411784 kg/gal
1,000 grams per cubic centimeter = 3,785.411784 kilograms per gallon.

Gram per Cubic Centimeter vs. Kilogram per Gallon
| Aspect | Gram per Cubic Centimeter | Kilogram per Gallon |
|---|---|---|
| Family | metric derived density unit | mixed metric/US customary density unit |
| Typical use | Material identification in chemistry and geology (mineral density tables) | 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 |
Understanding the Gram per Cubic Centimeter
