kg/m³ to g/cm³ (kg/m³ to g/cm³)
Result
0.001 g/cm³
Formula
g/cm³ = kg/m³ × 0.001
1 kg/m³ = 0.001 g/cm³, and 1 g/cm³ = 1,000 kg/m³.
Standard gravity is defined as exactly 9.80665 m/s². Density and flow factors follow from the length, mass and volume definitions (for example 1 US gallon per minute = 3.785411784 L/min).
Worked examples
- 1 kg/m³ × 0.001 = 0.001 g/cm³
- 10 kg/m³ × 0.001 = 0.01 g/cm³
- 100 kg/m³ × 0.001 = 0.1 g/cm³
Common mistakes
- Actual gravity varies from about 9.78 m/s² at the equator to 9.83 m/s² at the poles; "g" here is the defined standard value.
- GPM here means US gallons per minute; UK pump literature may use imperial gallons (4.546 L).
