About Converting Pounds per Cubic Centimeter to Pound per Cubic inches
Pound per Cubic Centimeter and Pound 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
pound per cubic inches = pounds per cubic centimeter × 16.387064
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 pound per cubic inch equals 27679.9047102 base units, so dividing one by the other gives the direct pound per cubic centimeter-to-pound per cubic inch factor of 16.387064.
Simple example
1 lb/cm3 × 16.387064 = 16.387064 lb/in3
1 pound per cubic centimeter = 16.387064 pound per cubic inches.
Real-world example
1,000 lb/cm3 × 16.387064 = 16,387.064 lb/in3
1,000 pounds per cubic centimeter = 16,387.064 pound per cubic inches.
