Expert Tip

Soil settles after watering and compaction. Always add a 10% volume safety buffer to your final purchase estimate.

Calculation Methodology & Details

📐

Formula

Imperial: cu yd = Length (ft) × Width (ft) × (Depth (in) / 12) / 27 Metric: cu m = Length (m) × Width (m) × (Depth (cm) / 100) Weight = Volume × Density

Determines rectangular soil volume. Weight calculations are based on the user-selected dry soil density (typically 75 - 90 lbs/cu ft).
