Density
Convert kilogram per cubic metre (kg/m³) to pound per US gallon (lb/US gal). Density is mass per unit volume — it links volumetric and mass flow, sets hydrostatic head, and drives pump and relief calculations.
1 kg/m³ = 0.008345404 lb/US gal
To convert kilogram per cubic metre to pound per US gallon, multiply the kg/m³ value by 0.008345404. To go the other way, divide by 0.008345404 (or multiply by 119.8264).
| kg/m³ | lb/US gal |
|---|---|
| 1 | 0.008345404 |
| 2 | 0.01669081 |
| 5 | 0.04172702 |
| 10 | 0.08345404 |
| 25 | 0.2086351 |
| 50 | 0.4172702 |
| 100 | 0.8345404 |
| 250 | 2.086351 |
| 500 | 4.172702 |
| 1000 | 8.345404 |
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 1000 kg/m³ is 8.345404 lb/US gal.
Multiply the value in kg/m³ by 0.008345404 to get lb/US gal. For example, 10 kg/m³ = 0.08345404 lb/US gal.
1 kg/m³ equals 0.008345404 lb/US gal.
