About Converting Kilograms per Gallon to Kilograms per Liter
Kilogram per Gallon and Kilogram per Liter 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
kilograms per liter = 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 kilogram per liter equals 1000 base units, so dividing one by the other gives the direct kilogram per gallon-to-kilogram per liter factor of 0.264172052358.
Simple example
1 kg/gal × 0.2641720524 = 0.2641720524 kg/L
1 kilogram per gallon = 0.2641720524 kilograms per liter.
Real-world example
1,000 kg/gal × 0.2641720524 = 264.1720524 kg/L
1,000 kilograms per gallon = 264.1720524 kilograms per liter.

Kilogram per Gallon vs. Kilogram per Liter
| Aspect | Kilogram per Gallon | Kilogram per Liter |
|---|---|---|
| Family | mixed metric/US customary density unit | metric derived density unit |
| Typical use | 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 | Fuel and petroleum density specifications (diesel is roughly 0.85 kg/L, gasoline roughly 0.74 kg/L) |
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
Understanding the Kilogram per Liter
Kilogram per Liter (kg/L) measures density. Numerically identical to grams per milliliter and to specific gravity for water-based substances, since water has a density of very nearly 1 kg/L. It is classified as a metric derived density unit.
Where it's used: Widely used internationally for fuel, oil, and food-industry density specifications
Uses of the Kilogram per Liter today
- Fuel and petroleum density specifications (diesel is roughly 0.85 kg/L, gasoline roughly 0.74 kg/L)
- Food and beverage industry quality control
- Quick density comparisons against water, since water is almost exactly 1 kg/L

Frequently asked questions
How many kilograms per liter are in 1 kilogram per gallon?
1 kilogram per gallon equals 0.2641720524 kilograms per liter, using the exact defined conversion factor rather than an estimate.
How do I convert kilogram per gallon to kilogram per liter?
Multiply the kilogram per gallon value by 0.2641720524. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per liter back to kilogram per gallon?
Use the reverse factor: 1 kilogram per liter 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 kilogram per liter?
Kilogram per Liter (kg/L) measures density. Numerically identical to grams per milliliter and to specific gravity for water-based substances, since water has a density of very nearly 1 kg/L. It is classified as a metric derived density unit.
Is the kilogram per gallon to kilogram per liter conversion exact?
Yes. Both kilogram per gallon and kilogram per liter 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.
