About Converting Gram per Cubic inches to Kilograms per Cup
Gram per Cubic inch 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 = gram per cubic inches × 0.0144375
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per cubic inch equals 61.0237440947 base units, and 1 kilogram per cup equals 4226.75283773 base units, so dividing one by the other gives the direct gram per cubic inch-to-kilogram per cup factor of 0.0144375.
Simple example
1 g/in3 × 0.0144375 = 0.0144375 kg/cup
1 gram per cubic inch = 0.0144375 kilograms per cup.
Real-world example
1,000 g/in3 × 0.0144375 = 14.4375 kg/cup
1,000 gram per cubic inches = 14.4375 kilograms per cup.

Frequently asked questions
How many kilograms per cup are in 1 gram per cubic inch?
1 gram per cubic inch equals 0.0144375 kilograms per cup, using the exact defined conversion factor rather than an estimate.
How do I convert gram per cubic inch to kilogram per cup?
Multiply the gram per cubic inch value by 0.0144375. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per cup back to gram per cubic inch?
Use the reverse factor: 1 kilogram per cup equals 69.26406926 gram per cubic inches. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per cubic inch?
Gram per Cubic inch (g/in3) is a unit of density.
What is a kilogram per cup?
Kilogram per Cup (kg/cup) is a unit of density.
Is the gram per cubic inch to kilogram per cup conversion exact?
Yes. Both gram per cubic inch and kilogram per cup are defined by fixed standards rather than physical artifacts, so the factor of 0.0144375 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.
