Density
Convert gram per cubic centimetre (g/cm³) 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 g/cm³ = 8.345404 lb/US gal
To convert gram per cubic centimetre to pound per US gallon, multiply the g/cm³ value by 8.345404. To go the other way, divide by 8.345404 (or multiply by 0.1198264).
| g/cm³ | lb/US gal |
|---|---|
| 1 | 8.345404 |
| 2 | 16.69081 |
| 5 | 41.72702 |
| 10 | 83.45404 |
| 25 | 208.6351 |
| 50 | 417.2702 |
| 100 | 834.5404 |
| 250 | 2086.351 |
| 500 | 4172.702 |
| 1000 | 8345.404 |
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 1 g/cm³ is 8.345404 lb/US gal.
Multiply the value in g/cm³ by 8.345404 to get lb/US gal. For example, 10 g/cm³ = 83.45404 lb/US gal.
1 g/cm³ equals 8.345404 lb/US gal.
