About Converting Decigrams per Cubic Centimeter to Kilograms per Gallon
Decigram 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. Both are mass per volume density units.
Formula
kilograms per gallon = decigrams per cubic centimeter × 0.3785411784
This factor comes from each unit's defined relationship to the category's base unit: 1 decigram per cubic centimeter equals 100 base units, and 1 kilogram per gallon equals 264.172052358 base units, so dividing one by the other gives the direct decigram per cubic centimeter-to-kilogram per gallon factor of 0.3785411784.
Simple example
1 dg/cm3 × 0.3785411784 = 0.3785411784 kg/gal
1 decigram per cubic centimeter = 0.3785411784 kilograms per gallon.
Real-world example
1,000 dg/cm3 × 0.3785411784 = 378.5411784 kg/gal
1,000 decigrams per cubic centimeter = 378.5411784 kilograms per gallon.

Understanding the Decigram per Cubic Centimeter (dg/cm3)
Mass per volume density.
Understanding the 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.
Uses of the Kilogram per Gallon today
- 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
Kilogram per Gallon — sources
- Fuel and petroleum liquid-density references — Liquid density figures for fuels are typically reported in kg/L, kg/m³, or lb/gal rather than kg/gal.

Frequently asked questions
How many kilograms per gallon are in 1 decigram per cubic centimeter?
1 decigram per cubic centimeter equals 0.3785411784 kilograms per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert decigram per cubic centimeter to kilogram per gallon?
Multiply the decigram per cubic centimeter value by 0.3785411784. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per gallon back to decigram per cubic centimeter?
Use the reverse factor: 1 kilogram per gallon equals 2.641720524 decigrams per cubic centimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a decigram per cubic centimeter?
Decigram per Cubic Centimeter (dg/cm3) is a unit of density.
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.
Is the decigram per cubic centimeter to kilogram per gallon conversion exact?
Yes. Both decigram per cubic centimeter and kilogram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.3785411784 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.
