kg/m³ to lb/ft³ (kg/m³ to lb/ft³)
Result
0.06242796058 lb/ft³
Formula
lb/ft³ = kg/m³ × 0.06242796058
1 kg/m³ = 0.06242796058 lb/ft³, and 1 lb/ft³ = 16.01846337 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 × 0.06242796058 = 0.062427961 lb/ft³
- 10 kg/m³ × 0.06242796058 = 0.62427961 lb/ft³
- 100 kg/m³ × 0.06242796058 = 6.2427961 lb/ft³
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).
