Density
Convert pound per cubic foot (lb/ft³) to kilogram per cubic metre (kg/m³). Density is mass per unit volume — it links volumetric and mass flow, sets hydrostatic head, and drives pump and relief calculations.
1 lb/ft³ = 16.01846 kg/m³
To convert pound per cubic foot to kilogram per cubic metre, multiply the lb/ft³ value by 16.01846. To go the other way, divide by 16.01846 (or multiply by 0.06242796).
| lb/ft³ | kg/m³ |
|---|---|
| 1 | 16.01846 |
| 2 | 32.03693 |
| 5 | 80.09231 |
| 10 | 160.1846 |
| 25 | 400.4616 |
| 50 | 800.9232 |
| 100 | 1601.846 |
| 250 | 4004.616 |
| 500 | 8009.231 |
| 1000 | 16018.46 |
Liquid densities are quoted in kg/m³ or as specific gravity; gas densities are much smaller and pressure-dependent.
Density converts a volumetric flow to a mass flow and vice versa — the single most common bridge in a material balance.
Worked example. A density of 62.42796 lb/ft³ is 1000 kg/m³.
Multiply the value in lb/ft³ by 16.01846 to get kg/m³. For example, 10 lb/ft³ = 160.1846 kg/m³.
1 lb/ft³ equals 16.01846 kg/m³.
