About Converting Kilogram per Cubic inches to Pounds per Cubic Centimeter
Kilogram per Cubic inch and Pound per Cubic Centimeter 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
pounds per cubic centimeter = kilogram per cubic inches × 0.134534326701
This factor comes from each unit's defined relationship to the category's base unit: 1 kilogram per cubic inch equals 61023.7440947 base units, and 1 pound per cubic centimeter equals 453592.37 base units, so dividing one by the other gives the direct kilogram per cubic inch-to-pound per cubic centimeter factor of 0.134534326701.
Simple example
1 kg/in3 × 0.1345343267 = 0.1345343267 lb/cm3
1 kilogram per cubic inch = 0.1345343267 pounds per cubic centimeter.
Real-world example
1,000 kg/in3 × 0.1345343267 = 134.5343267 lb/cm3
1,000 kilogram per cubic inches = 134.5343267 pounds per cubic centimeter.

How do I convert pound per cubic centimeter back to kilogram per cubic inch?
Use the reverse factor: 1 pound per cubic centimeter equals 7.433047197 kilogram per cubic inches. You can also use the swap control in the converter above to flip the direction instantly.
What is a kilogram per cubic inch?
Kilogram per Cubic inch (kg/in3) is a unit of density.
What is a pound per cubic centimeter?
Pound per Cubic Centimeter (lb/cm3) is a unit of density.
Is the kilogram per cubic inch to pound per cubic centimeter conversion exact?
Yes. Both kilogram per cubic inch and pound per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.1345343267 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.
