How this calculator works
Use finished coverage dimensions and depth. The displayed weight depends on your chosen soil density; wet soil can be much heavier.
Formula
Length × width × depth in inches ÷ 12 ÷ 27 × (1 + extra percentage).
Before you use the result
Calculator outputs are estimates based on the numbers you provide. Replace the examples with measurements, costs, rates, or product information appropriate to your situation.
Keep in mind
Soil compaction, moisture, and local delivery increments can materially affect the amount to order.
