About Converting Carats per Gallon to Kilograms per Cup
Carat 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. Both are mass per volume density units.
Formula
kilograms per cup = carats per gallon × 0.0000125
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per gallon equals 0.0528344104716 base units, and 1 kilogram per cup equals 4226.75283773 base units, so dividing one by the other gives the direct carat per gallon-to-kilogram per cup factor of 0.0000125.
Simple example
1 ct/gal × 0.0000125 = 0.0000125 kg/cup
1 carat per gallon = 0.0000125 kilograms per cup.
Real-world example
1,000 ct/gal × 0.0000125 = 0.0125 kg/cup
1,000 carats per gallon = 0.0125 kilograms per cup.

Frequently asked questions
How many kilograms per cup are in 1 carat per gallon?
1 carat per gallon equals 0.0000125 kilograms per cup, using the exact defined conversion factor rather than an estimate.
How do I convert carat per gallon to kilogram per cup?
Multiply the carat per gallon value by 0.0000125. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per cup back to carat per gallon?
Use the reverse factor: 1 kilogram per cup equals 80,000 carats per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per gallon?
Carat per Gallon (ct/gal) is a unit of density.
What is a kilogram per cup?
Kilogram per Cup (kg/cup) is a unit of density.
Is the carat per gallon to kilogram per cup conversion exact?
Yes. Both carat per gallon and kilogram per cup are defined by fixed standards rather than physical artifacts, so the factor of 0.0000125 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.
