Convert cubic feet to cubic yards or back, with options for cubic inches and cubic meters using standard volume conversion factors.
Assumptions Assumptions
- Conversions are volume-to-volume only—no density, compaction, or waste factors applied.
- Exact definitions used: 1 yd = 3 ft; 1 ft = 12 in; 1 in = 2.54 cm (exact), so 1 ft³ = 0.028316846592 m³ and 1 m³ = 35.31466672148859 ft³.
- US and Imperial feet/yards are identical by definition; no regional variants apply.
- Inputs are treated as precise geometric volumes (no shape assumptions).
When to Use This Calculator
- Estimating concrete, soil, mulch, or aggregate volumes for projects.
- Converting excavation or shipment specs between ft³ and yd³.
- Normalizing engineering, landscaping, or construction quantities across unit systems.
Input Definitions
- Cubic Feet (ft³) — left field; choose units ft³, yd³, in³, or m³ from the dropdown to convert.
- Cubic Yards (yd³) — right field; choose units ft³, yd³, in³, or m³ from the dropdown to convert.
- Conversions — yd³ = ft³ ÷ 27; ft³ = yd³ × 27; ft³ = in³ ÷ 1728; m³ = ft³ × 0.028316846592.

Ft^3 to Yd^3 Formula
The following formulas convert cubic feet to cubic yards and back.
yd³ = (ft³) / (27)
ft³ = 27 yd³
- 1 cubic yard = 27 cubic feet
- 1 cubic foot = 1/27 cubic yard (≈ 0.037037 yd³)
- 1 cubic foot = 1,728 cubic inches
- 1 cubic foot = 0.028316846592 cubic meters (exact)
How do you convert ft³ to yd³? Divide cubic feet by 27 to get cubic yards.
How do you convert yd³ to ft³? Multiply cubic yards by 27 to get cubic feet.
