Mulch, Soil, Compost and Firewood

Start with the area and the depth you want, and these calculators turn them into cubic feet, cubic yards and bags: mulch, topsoil and soil for a raised bed, and compost to spread. The cord calculator does the same for a stack of firewood. Prices are yours to enter, and each page names the source of its depths and conversion figures.
