Cubic Feet to Cubic Yards (ft³ to yd³)

Convert cubic feet to cubic yards with the simple divide-by-27 rule and a worked example.

Quick answer

yd³ = ft³ ÷ 27. Example: 32 ft³ ÷ 27 = 1.185… yd³.

Worked example

Example: You have 15 ft³ of soil. yd³ = 15/27 = 0.556 yd³ (approx).

Conversions are exact, but rounding is normal. For deliveries, round up to ensure enough material.

How many cubic yards is 40 cubic feet?

40/27=1.481… yd³.

Why 27?

Because 1 yard = 3 feet, and volume scales as 3×3×3 = 27.

Should I round up?

For deliveries, usually yes. For bag purchases, use bag math separately.

How many cubic yards is 54 cubic feet?

54 ft³ ÷ 27 = 2 yd³. Divide cubic feet by 27 to get cubic yards.
