Cubic Yard Conversion Sheet
Keep cubic feet, cubic yards, cubic metres and depth conversions together with area-times-depth formulas, checked examples and printable reference tables.
A reusable volume reference, with no material density or default waste allowance. Print the two-page sheet or keep it beside your calculator.
Volume conversions at a glance
1 yd = 3 ft = 0.9144 m exactly. Therefore 1 yd³ = 27 ft³ = 0.764554857984 m³ exactly. One cubic metre is approximately 1.307951 yd³.
These use the international foot (0.3048 m) and inch (0.0254 m), not the former U.S. survey foot. NIST lists rounded derived cubic factors; this sheet derives them from the exact length definitions. Table outputs are rounded to six decimal places; do not round intermediate calculations.
Cubic feet ↔ cubic yards
ft³ ÷ 27 = yd³; yd³ × 27 = ft³.
| Input | ft³ → yd³ | yd³ → ft³ |
|---|---|---|
| 0.25 | 0.009259 | 6.75 |
| 0.5 | 0.018519 | 13.5 |
| 1 | 0.037037 | 27 |
| 2 | 0.074074 | 54 |
| 5 | 0.185185 | 135 |
| 10 | 0.37037 | 270 |
| 27 | 1 | 729 |
| 50 | 1.851852 | 1350 |
| 100 | 3.703704 | 2700 |
Use the input as ft³ for the middle column or as yd³ for the right column.
Cubic metres ↔ cubic yards
m³ ÷ 0.764554857984 = yd³; reverse by multiplication.
| Input | m³ → yd³ | yd³ → m³ |
|---|---|---|
| 0.25 | 0.326988 | 0.191139 |
| 0.5 | 0.653975 | 0.382277 |
| 1 | 1.307951 | 0.764555 |
| 2 | 2.615901 | 1.52911 |
| 5 | 6.539753 | 3.822774 |
| 10 | 13.079506 | 7.645549 |
| 27 | 35.314667 | 20.642981 |
| 50 | 65.397531 | 38.227743 |
| 100 | 130.795062 | 76.455486 |
Use the input as m³ for the middle column or as yd³ for the right column.
Depth, area and worked examples
Common depths
1 in = 2.54 cm exactly; 12 in = 1 ft. These are conversions, not recommended construction depths.
| Inches | Feet | Centimetres | Metres |
|---|---|---|---|
| 1 | 0.083333 | 2.54 | 0.0254 |
| 2 | 0.166667 | 5.08 | 0.0508 |
| 3 | 0.25 | 7.62 | 0.0762 |
| 4 | 0.333333 | 10.16 | 0.1016 |
| 6 | 0.5 | 15.24 | 0.1524 |
| 8 | 0.666667 | 20.32 | 0.2032 |
| 12 | 1 | 30.48 | 0.3048 |
Area × depth formulas
- Square feet + inches: yd³ = area (ft²) × depth (in) ÷ 324.
- Square feet + feet: yd³ = area (ft²) × depth (ft) ÷ 27.
- Square metres + centimetres: m³ = area (m²) × depth (cm) ÷ 100; then divide by 0.764554857984 for yd³.
- Square metres + metres: m³ = area (m²) × depth (m).
Depth must represent the measured or specified geometry. Split varying-depth or irregular areas into suitable sections; do not assume one depth represents the whole site.
Check the steps
- 100 ft² at 4 in: depth = 4 ÷ 12 ft; volume = 100 × (4 ÷ 12) = 33.333333 ft³; divide the unrounded value by 27 → 1.234568 yd³.
- 108 ft² at 3 in: 108 × 3 ÷ 324 = 1 yd³ = 27 ft³ = 0.764554857984 m³.
- 12 m² at 10 cm: 12 × 10 ÷ 100 = 1.2 m³; 1.2 ÷ 0.764554857984 → 1.569541 yd³.
Geometric volume is not mass, material yield or an order quantity. This sheet assumes no density, compaction, bag yield, waste percentage, price or delivery minimum. Confirm site measurements and supplier requirements separately.
