How It Works

Density Converter

Conversion Factors from kg/m³

  • lb/ft³: kg/m³ × 0.062428
  • g/cm³: kg/m³ / 1,000
  • g/mL: kg/m³ / 1,000 (same as g/cm³)
  • lb/gal: kg/m³ × 0.00834541
  • Note: The density of water at 4°C is approximately 1000 kg/m³ = 1 g/cm³.

    Worked Example

    Convert 1000 kg/m³ (water) to other density units.

    value = 1000
    1. 01lb/ft³ = 1000 × 0.062428 = 62.428 lb/ft³
    2. 02g/cm³ = 1000 / 1000 = 1 g/cm³
    3. 03lb/gal = 1000 × 0.00834541 = 8.3454 lb/gal

    Frequently Asked Questions
