lb/ft³ to kg/m³ (lb/ft³ to kg/m³)
Result
16.01846337 kg/m³
Formula
kg/m³ = lb/ft³ × 16.01846337
1 lb/ft³ = 16.01846337 kg/m³, and 1 kg/m³ = 0.06242796058 lb/ft³.
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 lb/ft³ × 16.01846337 = 16.018463 kg/m³
- 10 lb/ft³ × 16.01846337 = 160.18463 kg/m³
- 100 lb/ft³ × 16.01846337 = 1,601.8463 kg/m³
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).
