Convert Square Feet to Cubic Yards Instantly

This square feet to cubic yards converter helps you convert area measurements (ft²) into volume (yd³) by including the depth of the material. This is the correct and only way to calculate cubic yards from square feet because cubic yards measure volume, not area.

Whether you're estimating mulch, gravel, soil, sand, concrete, or landscaping materials, this calculator delivers fast and accurate results.

How to Convert Square Feet to Cubic Yards

You must include depth to convert square feet into cubic yards.

Formula

Cubic Yards = (Square Feet × Depth in Feet) ÷ 27

Because:

• 1 cubic yard = 27 cubic feet
• Square feet × depth = cubic feet

Once you know cubic feet, divide by 27 to get cubic yards.

Example Conversions

Here are some real-world examples:

Square Feet	Depth (ft)	Cubic Yards
100 sq ft	1 ft	3.7037 yd³
50 sq ft	0.5 ft	0.9259 yd³
200 sq ft	2 ft	14.8148 yd³
300 sq ft	0.25 ft	2.7778 yd³

The calculator above performs these calculations instantly and formats the results cleanly.

Why You Need Depth for This Conversion

Square feet measure area, while cubic yards measure volume.
To convert area into volume, you must include a third dimension:

• Length
• Width
• Depth or thickness

This is especially important when calculating:

• Mulch coverage
• Soil fill
• Gravel or stone
• Sand
• Concrete
• Landscape materials
• Construction backfill

Without depth, the conversion would be incomplete or inaccurate.
