lb/ft³ to g/cm³ (lb/ft³ to g/cm³)
Result
0.01601846337 g/cm³
Formula
g/cm³ = lb/ft³ × 0.01601846337
1 lb/ft³ = 0.01601846337 g/cm³, and 1 g/cm³ = 62.42796058 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 × 0.01601846337 = 0.016018463 g/cm³
- 10 lb/ft³ × 0.01601846337 = 0.16018463 g/cm³
- 100 lb/ft³ × 0.01601846337 = 1.6018463 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).
