## Quick Reference Table ## Conversion Steps To change kg/m³ to g/cm³, divide by 1000. Since 1 m³ equals 1,000,000 cm³ and 1 kg equals 1000 g, the factor simplifies to 0.001. For reverse (g/cm³ to kg/m³), multiply by 1000. Example: 500 kg/m³ ÷ 1000 = 0.5 g/cm³.[page:1][page:2][page:3] ## Example Calculations – 1200 kg/m³ ÷ 1000 = 1.2 g/cm³ (gasoline density).[page:3] – 19300 kg/m³ ÷ 1000 = 19.3 g/cm³ (gold density).[page:3] – 1 g/cm³ × 1000 = 1000 kg/m³ (water at standard conditions).[page:1] ## Related Units Convert kg/m³ or g/cm³ to these density measures: – kg/L (multiply g/cm³ by 1) – g/L (divide kg/m³ by 1) – lb/ft³ (multiply kg/m³ by 0.06243) – oz/in³ (multiply g/cm³ by 0.578).[page:1] ## Popular Conversions – Air at sea level: 1.2 kg/m³ = 0.0012 g/cm³ – Steel: 7850 kg/m³ = 7.85 g/cm³ – Mercury: 13600 kg/m³ = 13.6 g/cm³ – Ice: 917 kg/m³ = 0.917 g/cm³[page:2][page:3] ## Frequently Asked Questions **Why divide by 1000 for kg/m³ to g/cm³?** 1 m³ = 10^6 cm³, so volume scales by 10^6. Mass scales by 10^-3 (kg to g), netting 10^-3 factor.[page:1][page:2] **What density is pure water?** 1000 kg/m³ or 1 g/cm³ exactly at 4°C.[page:3] **Can negative values work?** Input accepts them for hypothetical gases or calculations. **Accuracy for large numbers?** Handles up to JavaScript precision limits; round as needed. ## References National Institute of Standards and Technology.
