Density
Convert pound per US gallon (lb/US gal) to gram per cubic centimetre (g/cm³). 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 = 0.1198264 g/cm³
To convert pound per US gallon to gram per cubic centimetre, multiply the lb/US gal value by 0.1198264. To go the other way, divide by 0.1198264 (or multiply by 8.345404).
| lb/US gal | g/cm³ |
|---|---|
| 1 | 0.1198264 |
| 2 | 0.2396529 |
| 5 | 0.5991321 |
| 10 | 1.198264 |
| 25 | 2.995661 |
| 50 | 5.991321 |
| 100 | 11.98264 |
| 250 | 29.95661 |
| 500 | 59.91321 |
| 1000 | 119.8264 |
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 1 g/cm³.
Multiply the value in lb/US gal by 0.1198264 to get g/cm³. For example, 10 lb/US gal = 1.198264 g/cm³.
1 lb/US gal equals 0.1198264 g/cm³.
