About Pound per gallon (lb/gal)

A liquid-density unit (lb per US gallon, abbreviated lb/gal or ppg in oilfield jargon) heavily used in US industry. Reference values: fresh water at 60 °F is 8.345 lb/gal (the universal calibration baseline), sea water ~8.55 lb/gal, gasoline ~6.15 lb/gal, kerosene/Jet A 6.5-6.8 lb/gal, diesel 6.9-7.1 lb/gal, milk ~8.6 lb/gal. The dominant industrial use is drilling-mud density in oil and gas operations: API RP 13B and the IADC mud-handling tables specify mud weight in ppg, and the hydrostatic-pressure formula in psi/ft is mud weight × 0.052 directly. Drillers chase a mud weight just heavy enough to control pore pressure but not heavy enough to fracture the formation (the 'mud window'). Lb/gal also appears in paints/coatings (VOC compliance reporting), industrial cleaners, and beer/wort specific-gravity work (homebrew + craft-brewing). Convert: 1 lb/gal = 119.83 kg/m³ = 0.1198 g/mL.

About Gram per cubic centimeter (g/cm³)

A CGS-system density unit numerically equal to specific gravity relative to water at 4 °C (water = 1.000 g/cm³ by the original 1795 kilogram definition). 1 g/cm³ = 1,000 kg/m³, making the conversion between this CGS unit and the SI trivial. Widely used in geology (sedimentary rock 2.0-2.7 g/cm³, granite 2.65-2.75, basalt 2.8-3.0), crystallography and gemology (diamond 3.52 g/cm³, ruby and sapphire 4.00, opal 1.98-2.25 — density is the primary non-destructive ID method for cut gemstones), polymer chemistry (HDPE 0.94-0.97, PP 0.85-0.95, PET 1.37-1.45, PVC 1.30-1.45), and the wine, beer, and spirits industry where density is reported as specific gravity (final-gravity vs original-gravity readings drive ABV calculation). Petroleum: API gravity is defined directly from g/cm³ as °API = (141.5 / SG) − 131.5.

Understanding Grams per cubic centimeter

The Gram per cubic centimeter (symbol: g/cm³) is a unit of density. A CGS-system density unit numerically equal to specific gravity relative to water at 4 °C (water = 1.000 g/cm³ by the original 1795 kilogram definition). 1 g/cm³ = 1,000 kg/m³, making the conversion between this CGS unit and the SI trivial. Widely used in geology (sedimentary rock 2.0-2.7 g/cm³, granite 2.65-2.75, basalt 2.8-3.0), crystallography and gemology (diamond 3.52 g/cm³, ruby and sapphire 4.00, opal 1.98-2.25 — density is the primary non-destructive ID method for cut gemstones), polymer chemistry (HDPE 0.94-0.97, PP 0.85-0.95, PET 1.37-1.45, PVC 1.30-1.45), and the wine, beer, and spirits industry where density is reported as specific gravity (final-gravity vs original-gravity readings drive ABV calculation).
