About Kilogram per Cubic Meter and Pound per Cubic Inch

The kilogram per cubic meter is the SI derived unit of density. Air is about 1.2 kg/m³ and water about 1,000 kg/m³; engineering tables list materials in this unit. 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. One Kilogram per Cubic Meter equals 0.000036127292 Pound per Cubic Inch (1 kg-m3 = 0.000036127292 lb-in3). Kilogram per Cubic Meter is used in engineering material tables and in air density in aerodynamics. Pound per Cubic Inch is used in US machining stock weight.

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).
