About Converting Grams per Cubic Centimeter to Kilograms per Imperial gallon
Gram per Cubic Centimeter and Kilogram per Imperial 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 imperial gallon = grams per cubic centimeter × 4.54609
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 imperial gallon equals 219.969248299 base units, so dividing one by the other gives the direct gram per cubic centimeter-to-kilogram per imperial gallon factor of 4.54609.
Simple example
1 g/cm3 × 4.54609 = 4.54609 kg/imp gal
1 gram per cubic centimeter = 4.54609 kilograms per imperial gallon.
Real-world example
1,000 g/cm3 × 4.54609 = 4,546.09 kg/imp gal
1,000 grams per cubic centimeter = 4,546.09 kilograms per imperial gallon.

Frequently asked questions
How many kilograms per imperial gallon are in 1 gram per cubic centimeter?
1 gram per cubic centimeter equals 4.54609 kilograms per imperial gallon, using the exact defined conversion factor rather than an estimate.
How do I convert gram per cubic centimeter to kilogram per imperial gallon?
Multiply the gram per cubic centimeter value by 4.54609. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per imperial gallon back to gram per cubic centimeter?
Use the reverse factor: 1 kilogram per imperial gallon equals 0.2199692483 grams per cubic centimeter. You can also use the swap control in the converter above to flip the direction instantly.
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 kilogram per imperial gallon?
Kilogram per Imperial gallon (kg/imp gal) measures density. A mathematically valid way to express liquid density in kilograms per imperial gallon. It is classified as a mixed metric/UK customary density unit.
Is the gram per cubic centimeter to kilogram per imperial gallon conversion exact?
Yes. Both gram per cubic centimeter and kilogram per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 4.54609 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.
