Kilograms per cubic meter to Grams per cubic centimeter (kg/m³ to g/cm³)

Convert kilograms per cubic meter to grams per cubic centimeter: 1 kg/m³ = 0.001 g/cm³. Exact conversion factor, formula, 22-row table and worked examples, with JSON API and MCP access.

Formula

1 kg/m³ = 0.001 g/cm³

grams per cubic centimeter = kilograms per cubic meter × 0.001 — reverse: kilograms per cubic meter = grams per cubic centimeter × 1000

The factor is derived from the SI definitions of both units (base unit: kg/m3) as listed in NIST SP 811; results on this page are shown to 6 significant figures, the API returns up to 12.

Worked examples

5 kg/m³ = 0.005 g/cm³
12.5 kg/m³ = 0.0125 g/cm³
100 kg/m³ = 0.1 g/cm³
