Calculate soil volume and weight for raised beds, containers, or greenhouse benches. Enter dimensions and bulk density.
Enter length, width, depth, and bulk density to find soil volume in cubic feet/yards and total weight.
Volume (cu ft) = Length × Width × (Depth in ÷ 12)
Weight (lb) = Volume × Bulk Density × 62.4
20×10 ft bed, 6 in deep: Volume = 20×10×0.5 = 100 cu ft = 3.70 cu yd. At 1.3 g/cm³: 8,112 lb = 4.06 tons.
1. Enter length and width in feet. 2. Depth in inches. 3. Bulk density (1.1-1.4 mineral soil, 0.4-0.8 potting mix). Calculate.
Accurate volume prevents over-ordering or under-ordering. Bulk density varies — potting mix weighs 40-60% less than field soil.
Using field soil density for potting mix. Forgetting soil settling — order 10-15% extra.
