About Converting Ounce per Cubic inches to Kilograms per Quart
Ounce per Cubic inch and Kilogram per Quart 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 quart = ounce per cubic inches × 1.63718496047
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per cubic inch equals 1729.99404439 base units, and 1 kilogram per quart equals 1056.68820943 base units, so dividing one by the other gives the direct ounce per cubic inch-to-kilogram per quart factor of 1.63718496047.
Simple example
1 oz/in3 × 1.63718496 = 1.63718496 kg/qt
1 ounce per cubic inch = 1.63718496 kilograms per quart.
Real-world example
1,000 oz/in3 × 1.63718496 = 1,637.18496 kg/qt
1,000 ounce per cubic inches = 1,637.18496 kilograms per quart.

How do I convert kilogram per quart back to ounce per cubic inch?
Use the reverse factor: 1 kilogram per quart equals 0.6108045359 ounce per cubic inches. You can also use the swap control in the converter above to flip the direction instantly.
What is a ounce per cubic inch?
Ounce per Cubic inch (oz/in3) is a unit of density.
What is a kilogram per quart?
Kilogram per Quart (kg/qt) is a unit of density.
Is the ounce per cubic inch to kilogram per quart conversion exact?
Yes. Both ounce per cubic inch and kilogram per quart are defined by fixed standards rather than physical artifacts, so the factor of 1.63718496 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.
