Quick Answer
1 cubic yard = 27 cubic feet.
To convert cubic yards to cubic feet, multiply the number of cubic yards by 27.
Formula:
Cubic Feet = Cubic Yards × 27
For example:
- 1 cubic yard = 27 cubic feet
- 2 cubic yards = 54 cubic feet
- 5 cubic yards = 135 cubic feet
Why Does 1 Cubic Yard Equal 27 Cubic Feet?
A yard measures 3 feet. Since volume measures length, width, and height, you multiply all three dimensions:
3 feet × 3 feet × 3 feet = 27 cubic feet
Imagine a cube that is:
- 3 feet long
- 3 feet wide
- 3 feet high
The total volume is:
3 × 3 × 3 = 27 cubic feet
This is exactly 1 cubic yard.

What Is a Cubic Yard?
A cubic yard is a unit of volume commonly used in:
- Landscaping
- Construction
- Concrete projects
- Gravel delivery
- Mulch calculations
- Soil measurements
- Compost
- Sand purchases
One cubic yard represents a cube measuring:
- 3 feet long
- 3 feet wide
- 3 feet high
Since each side is 3 feet, the total volume equals 27 cubic feet.
What Is a Cubic Foot?
A cubic foot is the volume of a cube measuring:
- 1 foot long
- 1 foot wide
- 1 foot high
Its volume equals:
1 × 1 × 1 = 1 cubic foot
Because a cubic yard contains 27 of these smaller cubes, 1 cubic yard equals 27 cubic feet.
Formula to Convert Cubic Yards to Cubic Feet
Use this simple formula:
Cubic Feet = Cubic Yards × 27
Examples
Example 1
2 cubic yards
2 × 27 = 54 cubic feet
Example 2
6 cubic yards
6 × 27 = 162 cubic feet
Example 3
12 cubic yards
12 × 27 = 324 cubic feet
Formula to Convert Cubic Feet to Cubic Yards
Sometimes you need the reverse calculation.
Cubic Yards = Cubic Feet ÷ 27
Examples
54 cubic feet ÷ 27 = 2 cubic yards
135 cubic feet ÷ 27 = 5 cubic yards
270 cubic feet ÷ 27 = 10 cubic yards
Why This Conversion Matters
Knowing how many cubic feet are in a cubic yard helps you:
- Order the correct amount of mulch
- Estimate concrete needs
- Buy enough gravel
- Calculate soil volume
- Compare bagged products with bulk materials
- Avoid overspending on landscaping supplies
Many suppliers sell materials by the cubic yard, while bags list their volume in cubic feet.
Common Landscaping Examples
Mulch
A typical bag contains 2 cubic feet.
Since one cubic yard equals 27 cubic feet:
27 ÷ 2 = 13.5 bags
You’ll need about 14 bags to equal one cubic yard.
Garden Soil
If a raised garden bed requires 54 cubic feet:
54 ÷ 27 = 2 cubic yards
Ordering two cubic yards is easier than buying dozens of small bags.
Gravel
Suppose your driveway project requires 81 cubic feet.
81 ÷ 27 = 3 cubic yards
This is the amount you should order from a supplier.
Concrete Example
Imagine pouring a patio measuring:
- Length: 9 feet
- Width: 6 feet
- Thickness: 6 inches (0.5 feet)
Volume:
9 × 6 × 0.5 = 27 cubic feet
Since 27 cubic feet equals one cubic yard, you’ll need approximately 1 cubic yard of concrete.
Cubic Yard vs Cubic Foot
| Feature | Cubic Foot | Cubic Yard |
|---|---|---|
| Symbol | ft³ | yd³ |
| Size | Small volume | Large volume |
| Equivalent | 1 ft³ | 27 ft³ |
| Common Uses | Bagged soil, storage | Bulk gravel, concrete, mulch |
Practical Uses Around the Home
Homeowners frequently use this conversion for:
- Filling flower beds
- Installing playground mulch
- Building retaining walls
- Creating raised garden beds
- Filling planter boxes
- Pouring sidewalks
- Installing patios
- Leveling lawns
Understanding the conversion helps estimate materials accurately.
Construction Applications
Contractors use cubic yards for:
- Concrete deliveries
- Excavation estimates
- Backfill calculations
- Sand orders
- Stone delivery
- Demolition debris
- Foundation work
Meanwhile, architectural plans sometimes reference cubic feet. Knowing the conversion prevents costly mistakes.
Conversion Table for Larger Volumes
| Cubic Yards | Cubic Feet |
|---|---|
| 25 | 675 |
| 30 | 810 |
| 40 | 1,080 |
| 50 | 1,350 |
| 75 | 2,025 |
| 100 | 2,700 |
Step-by-Step Conversion Example
Suppose a supplier offers 4 cubic yards of topsoil.
Step 1: Write the formula.
Cubic Feet = Cubic Yards × 27
Step 2: Insert the value.
4 × 27
Step 3: Calculate.
= 108 cubic feet
Your delivery contains 108 cubic feet of soil.
Common Mistakes to Avoid
Forgetting That Volume Is Three-Dimensional
Some people multiply by 3 instead of 27.
Remember:
3 × 3 × 3 = 27
Mixing Square Feet and Cubic Feet
Square feet measure area.
Cubic feet measure volume.
These units cannot be used interchangeably.
Ordering Too Little Material
Always add about 5–10% extra when ordering gravel, mulch, or soil to account for settling, uneven surfaces, and waste.
Expert Tips
- Measure carefully before ordering materials.
- Double-check whether suppliers sell by cubic yards or cubic feet.
- Round up when purchasing bulk materials.
- Use online volume calculators for complex shapes.
- Keep the 27-to-1 conversion in mind for quick estimates.
Real-World Example
You’re installing mulch in a large landscape.
Your calculations show you need 135 cubic feet.
Convert to cubic yards:
135 ÷ 27 = 5 cubic yards
Instead of purchasing approximately 68 bags of 2-cubic-foot mulch, ordering 5 cubic yards delivered in bulk is usually more affordable and convenient.
