About Converting Kilograms per Gallon to Kilograms per Cup
Kilogram per Gallon and Kilogram per Cup 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 cup = kilograms per gallon × 0.0625
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 cup equals 4226.75283773 base units, so dividing one by the other gives the direct kilogram per gallon-to-kilogram per cup factor of 0.0625.
Simple example
1 kg/gal × 0.0625 = 0.0625 kg/cup
1 kilogram per gallon = 0.0625 kilograms per cup.
Real-world example
1,000 kg/gal × 0.0625 = 62.5 kg/cup
1,000 kilograms per gallon = 62.5 kilograms per cup.

Frequently asked questions
How many kilograms per cup are in 1 kilogram per gallon?
1 kilogram per gallon equals 0.0625 kilograms per cup, using the exact defined conversion factor rather than an estimate.
How do I convert kilogram per gallon to kilogram per cup?
Multiply the kilogram per gallon value by 0.0625. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per cup back to kilogram per gallon?
Use the reverse factor: 1 kilogram per cup equals 16 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 cup?
Kilogram per Cup (kg/cup) is a unit of density.
Is the kilogram per gallon to kilogram per cup conversion exact?
Yes. Both kilogram per gallon and kilogram per cup are defined by fixed standards rather than physical artifacts, so the factor of 0.0625 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.
