About Converting Pounds per Cubic Centimeter to Kilogram per Cubic inches
Pound per Cubic Centimeter 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 = pounds per cubic centimeter × 7.4330471971
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cubic centimeter equals 453592.37 base units, and 1 kilogram per cubic inch equals 61023.7440947 base units, so dividing one by the other gives the direct pound per cubic centimeter-to-kilogram per cubic inch factor of 7.4330471971.
Simple example
1 lb/cm3 × 7.433047197 = 7.433047197 kg/in3
1 pound per cubic centimeter = 7.433047197 kilogram per cubic inches.
Real-world example
1,000 lb/cm3 × 7.433047197 = 7,433.047197 kg/in3
1,000 pounds per cubic centimeter = 7,433.047197 kilogram per cubic inches.

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