Complete Android Modulus reference: constants for Construction.
Common engineering references
• g ≈ 9.81 m/s²
• water density ρ ≈ 1000 kg/m³
• steel density ρ ≈ 7850 kg/m³
• concrete density ρ ≈ 2200…2500 kg/m³
Comment
In construction many "constants" depend on grade, moisture, temperature, and standard, so ranges are often more useful than a single value.
