About Converting Ounce per Cubic inches to Kilogram per Cubic inches
Ounce per Cubic inch and Kilogram per Cubic inch 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
kilogram per cubic inches = ounce per cubic inches × 0.028349523125
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 cubic inch equals 61023.7440947 base units, so dividing one by the other gives the direct ounce per cubic inch-to-kilogram per cubic inch factor of 0.028349523125.
Simple example
1 oz/in3 × 0.02834952313 = 0.0283495231 kg/in3
1 ounce per cubic inch = 0.0283495231 kilogram per cubic inches.
Real-world example
1,000 oz/in3 × 0.02834952313 = 28.34952313 kg/in3
1,000 ounce per cubic inches = 28.34952313 kilogram per cubic inches.

How do I convert kilogram per cubic inch back to ounce per cubic inch?
Use the reverse factor: 1 kilogram per cubic inch equals 35.27396195 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 cubic inch?
Kilogram per Cubic inch (kg/in3) is a unit of density.
Is the ounce per cubic inch to kilogram per cubic inch conversion exact?
Yes. Both ounce per cubic inch and kilogram per cubic inch are defined by fixed standards rather than physical artifacts, so the factor of 0.02834952313 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.
