Cubic Feet to Cubic Yards Converter

The conversion

1 cubic yard = 27 cubic feet (exact)

Cu yd = Cu ft ÷ 27

Cu ft = Cu yd × 27

How to calculate volume from area + depth

If you know area (sq ft) and depth (inches):

Cu ft = Area (sq ft) × Depth (in) ÷ 12

Cu yd = Cu ft ÷ 27 = Area × Depth (in) ÷ 324

Example: 100 sq ft at 3 inches = 100 × 3 ÷ 324 = 0.93 cubic yards
