About these calculators
Landscape materials are sold in a confusing mix of units: bagged mulch by the cubic foot or litre, bulk mulch and soil by the cubic yard or cubic metre, and stone by the ton or tonne. These calculators start from your measurements and give you each of those figures so you can compare suppliers.
Weights for stone and soil are always estimates, because moisture and grading change how much a cubic yard weighs. When a supplier sells by weight, ask for their conversion figure and enter it as the density.
