Density Converter

Convert between kg/m³, g/cm³, lb/ft³, lb/in³, and more

Density conversions are used in material science, fluid mechanics, quality control, and chemistry. Material specifications list density in kg/m³, while engineers often work in g/cm³ or lb/ft³ depending on their design environment. Knowing a material's density is critical for calculating weights, predicting buoyancy, selecting materials for weight-critical applications, and verifying incoming material quality through simple weight and volume measurements.

About Density Units

The SI unit of density is kg/m³. Compact materials are often expressed in g/cm³ (= 1,000 kg/m³). US engineering uses lb/ft³ and lb/in³. The density of water (1,000 kg/m³ = 1 g/cm³ at 4°C) serves as a convenient reference point for comparing material densities.
