g/cm³ to lb/ft³ (g/cm³ to lb/ft³)
Result
62.42796058 lb/ft³
Formula
lb/ft³ = g/cm³ × 62.42796058
1 g/cm³ = 62.42796058 lb/ft³, and 1 lb/ft³ = 0.01601846337 g/cm³.
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 g/cm³ × 62.42796058 = 62.427961 lb/ft³
- 10 g/cm³ × 62.42796058 = 624.27961 lb/ft³
- 100 g/cm³ × 62.42796058 = 6,242.7961 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).
