Square Feet to Cubic Yards
Find a uniform layer’s volume from its area and depth, in cubic yards and cubic meters.
Formula
V = area × depth; yd³ = ft² × depth(in) / 324
Area: 100 ft² · Depth: 4 in · Volume in cubic meters ≈ (100 ft² × 0.09290304 m²/ft²)×(4 in × 0.0254 m/in) · Volume in cubic yards ≈ (0.9438948864)÷0.764554857984
How to use
- Enter the area and its unit.
- Enter the uniform depth and its unit.
- Read the volume in yd³ and m³.
Examples
- 324 ft² at 1 in deep = 1 yd³.
Frequently asked questions
Can square feet convert directly to cubic yards?
No. Area needs a depth to determine volume.
Does this include waste or compaction?
No. Add any allowance separately using project or material guidance.
What if depth varies?
Divide the area into sections with known depths and add their volumes.
