Which density unit should I use?

kg/m³ is standard in SI, but g/cm³ is common in chemistry and lb/ft³ in the US/UK.

What is the difference between specific gravity and density?

Specific gravity is a dimensionless ratio relative to water density (at 4°C). Density is a physical quantity with units (kg/m³, etc.).

Pounds per cubic foot, a density unit in the imperial system. 1 lb/ft³ ≈ 16.0185 kg/m³.
