About Pound per Cubic Inch and Gram per Cubic Centimeter
The pound per cubic inch is 1,728 times denser than lb/ft³, about 27,680 kg/m³ — steel is roughly 0.28 lb/in³. US machining and aerospace use it for metal parts. The gram per cubic centimeter equals exactly 1,000 kg/m³, with water at about 1 g/cm³. Chemistry, mineralogy, and metallurgy quote densities in g/cm³ because values land in a convenient 0–20 range. One Pound per Cubic Inch equals 27.67990471 Gram per Cubic Centimeter (1 lb-in3 = 27.67990471 g-cm3). Pound per Cubic Inch to Gram per Cubic Centimeter conversion comes up most often in US machining stock weight and in aerospace component design, typically when figures need restating for chemistry lab work.
Precision and Rounding: Density conversions chain mass and volume factors, so imperial-metric results carry long decimals (1 lb/ft³ ≈ 16.0185 kg/m³). Material selection tolerates two decimals; chemical engineering, brewing, and aerospace specs need four or more significant figures.
Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
