One cubic yard contains 27 cubic feet because a yard is three feet in each dimension: 3 × 3 × 3 = 27. Divide cubic feet by 27 to get cubic yards; multiply cubic yards by 27 to return to cubic feet.
Divide cubic feet by 27 to get cubic yards. The relationship is exact because one yard is three feet and 3 × 3 × 3 = 27 cubic feet per cubic yard.

Cubic feet and cubic yards are volume units.
If the starting measurement is square feet, include material depth before converting.
Cubic yards = cubic feet ÷ 27.
For example, 270 cubic feet equals 10 cubic yards.
Avoid rounding intermediate geometry before the unit conversion.
Round at the supplier's actual sales unit after allowances are applied.
A cubic yard does not have one universal weight.
Material density, moisture, gradation, and compaction determine weight.
Excavated, loose, and compacted volumes can differ even when the unit is the same.
Record whether the quantity is bank, loose, or placed volume.
Convert feet, inches, and yards consistently in construction takeoffs and avoid mixing linear, square, and cubic unit relationships.
Read guide →Construction ConversionsConvert square feet to square yards for carpet, flooring, paving, and surface-area estimates using the exact 9-to-1 area relationship.
Read guide →Construction ConversionsConvert cubic yards to short tons with material-specific bulk density instead of using a universal yards-to-tons factor.

| Step | Result |
|---|---|
| Starting volume | 270 cu ft |
| Conversion | 270 ÷ 27 |
| Cubic yards | 10.00 cu yd |
| Procurement | Apply material-specific adjustments afterward |
Current manufacturer data, supplier specifications, drawings, field measurements, applicable codes, permit requirements, and qualified professional guidance can take priority over a general-purpose planning estimate.
