Density
Convert pound per US gallon (lb/US gal) 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/US gal = 119.8264 kg/m³
To convert pound per US gallon to kilogram per cubic metre, multiply the lb/US gal value by 119.8264. To go the other way, divide by 119.8264 (or multiply by 0.008345404).
| lb/US gal | kg/m³ |
|---|---|
| 1 | 119.8264 |
| 2 | 239.6529 |
| 5 | 599.1321 |
| 10 | 1198.264 |
| 25 | 2995.661 |
| 50 | 5991.321 |
| 100 | 11982.64 |
| 250 | 29956.61 |
| 500 | 59913.21 |
| 1000 | 119826.4 |
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 8.345404 lb/US gal is 1000 kg/m³.
Multiply the value in lb/US gal by 119.8264 to get kg/m³. For example, 10 lb/US gal = 1198.264 kg/m³.
1 lb/US gal equals 119.8264 kg/m³.
