Solution:
Density in kg/m³ = lb/gal × 119.826
= 12.5 × 119.826
= 1,498 kg/m³
Answer: 12.5 lb/gal = 1,498 kg/m³ — a medium-weight drilling fluid for moderately pressured formations.

API Gravity and Its Relationship to lb/gal
The petroleum industry uses API gravity to classify crude oils: API = (141.5 / SG) – 131.5, where SG = (lb/gal) / 8.345. Light crude (API > 31°) has density below 7.3 lb/gal (875 kg/m³), while heavy crude (API < 22.3°) exceeds 7.8 lb/gal (935 kg/m³). Pipeline operators use lb/gal for custody transfer metering because US volumetric measurements are in gallons.
Paint Weight Per Gallon and Coverage
Paint manufacturers report "weight per gallon" in lb/gal on every TDS (Technical Data Sheet). Higher-density paints (12–16 lb/gal) contain more pigment and fillers, providing better hiding power and coverage. A primer at 13.5 lb/gal (1,618 kg/m³) contains significant titanium dioxide content, while a clear coat at 8.5 lb/gal (1,018 kg/m³) is mostly resin and solvent. Specifiers compare lb/gal to evaluate paint quality.
Key Takeaways
- 1 lb/gal (US) = 119.826 kg/m³.
- Water = 8.34 lb/gal is the US reference for all fluid densities.
- Dominant unit in US petroleum, paint, and chemical industries.
- API gravity classification is derived from lb/gal measurements.
- Quick estimate: multiply lb/gal by 120.
