CALCULATOR
Square Feet to Cubic Yards Calculator
Find volume in cubic yards from square feet and depth in feet. Example: Area: 100 ft², Depth: 2 ft gives 7.40740740741 yd³. Depth in feet; 27 cubic feet per cubic yard. Waste and packing excluded. Flat Euclidean shape; stated measurements in displayed units. No waste, thickness, structural suitability or curved-earth claim. Floating point rounding is display only.
Depth in feet; 27 cubic feet per cubic yard. Waste and packing excluded. Flat Euclidean shape; stated measurements in displayed units. No waste, thickness, structural suitability or curved-earth claim. Floating point rounding is display only. Derivation: One yard=3 feet, so yd³=27 ft³; divide coherent cubic-foot volume by27.
Accepted inputs: Area: 0.001 to 100,000,000 ft²; Depth: 0.001 to 1,000 ft.
volume in cubic yards from square feet and depth in feet
How the calculation works
cubic yards = square feet × depth feet /27
Worked example
With area 100 ft², depth 2 ft, volume in cubic yards from square feet and depth in feet is 7.407407407 yd³.
Assumptions and limits
