Convert a floor area and depth straight into cubic yards of fill.
Already know your area in square feet? This tool converts it directly to cubic yards once you add a depth — perfect for ordering gravel, topsoil or concrete.
The math behind it
Multiply area by depth (in feet) to get cubic feet, then divide by 27 to get cubic yards.
Worked example
200 ft² at 3 in deep → 200 × (3/12) = 50 ft³ ÷ 27 = 1.85 yd³.
