Enter cubic feet or cubic yards into the calculator to convert ft^3 to yards.
Assumptions Assumptions
- Conversions are volume-to-volume; no packing, bulking, or material density adjustments.
- Unit standards used: 1 yd³ = 27 ft³; 1 ft³ = 1,728 in³; 1 m³ ≈ 35.3146667 ft³ ≈ 1.30795062 yd³.
- Results are rounded to 6 decimal places in the calculator for readability.
- Intended for geometric volume calculations (e.g., concrete, soil, mulch), not shipping allowances.
When to Use This Calculator
- Estimating concrete, soil, gravel, or mulch in cubic yards from measurements taken in cubic feet.
- Converting plan takeoffs or excavation volumes between ft³, yd³, m³, and in³.
- Standardizing project estimates across US customary and metric units.
Input Definitions
- Cubic Feet — select ft³ (0.028316846592 m³), in³ (0.000016387064 m³), or enter directly in m³.
- Cubic Yards — select yd³ (0.764554857984 m³), or convert via m³/ft³ as needed.
- Conversions — yd³ = ft³ ÷ 27; ft³ = yd³ × 27; in³ to ft³ = in³ ÷ 1,728.

Ft^3 to Yards Formula
The following formulas convert cubic feet to cubic yards and back, with exact US customary relationships and optional metric references.
\mathrm{yd}^{3} = \frac{\mathrm{ft}^{3}}{27}\mathrm{ft}^{3} = 27\,\mathrm{yd}^{3}- 1 cubic yard (yd³) = 27 cubic feet (ft³)
- 1 cubic foot (ft³) = 1,728 cubic inches (in³)
- 1 cubic meter (m³) ≈ 35.3146667 ft³
- 1 cubic meter (m³) ≈ 1.30795062 yd³
How do you convert cubic feet to cubic yards? Divide cubic feet by 27 to get cubic yards.
How do you convert cubic yards to cubic feet? Multiply cubic yards by 27 to get cubic feet.
