Technical Details: Gravel Calculator
The Gravel Calculator employs standard engineering formulas for volume and weight computations, ensuring reliability in construction estimations.
Volume is calculated as V = Length × Width × Depth (or Area × Depth, or direct input), converted to cubic feet using factors like 1 yd = 3 ft or 1 m = 3.28084 ft. A 10% wastage adjustment is applied: V_adjusted = V × 1.10. Weight follows W = V_adjusted × Density, where density varies by gravel type (e.g., 105 lb/ft³ for washed gravel), then converted to tons (W / 2000). Costs are derived from price per yd³ (V_adjusted / 27 × price) or per ton (W_tons × price), selecting the minimum for optimization.
These methods align with industry guidelines from sources like the U.S. Geological Survey (USGS) Mineral Commodity Summaries, which provide density benchmarks and production data for aggregates.
