About this calculator

For a round pot, soil volume is V = π × r² × h using the container's inner radius and fill height; for a rectangular planter it's simply V = length × width × height. The calculator converts the result into liters and cubic feet, the two units bagged potting soil is typically sold in.

Gardeners, landscapers, and nursery growers use this before buying soil for pots, raised beds, or planter boxes, so they can compare the container's volume against bag sizes and buy close to the right amount rather than guessing and ending up with several bags left over or a short trip back to the store.
