If you’re buying mulch, gravel, topsoil, concrete, or sand, you’ll likely need to convert between cubic feet and cubic yards. The good news is that the conversion is simple:
1 cubic yard = 27 cubic feet
Knowing this conversion can help you estimate materials accurately, save money, and avoid ordering too much or too little. Whether you’re working on a landscaping project, pouring concrete, or filling raised garden beds, understanding cubic measurements is essential.
What Is a Cubic Yard?
A cubic yard is a unit of volume commonly used in the United States for measuring bulk materials. Imagine a cube that measures:
- 3 feet long
- 3 feet wide
- 3 feet high
The total volume of this cube is:
3 × 3 × 3 = 27 cubic feet
That’s why one cubic yard always equals 27 cubic feet.
What Is a Cubic Foot?
A cubic foot measures the volume of a cube that is:
- 1 foot long
- 1 foot wide
- 1 foot high
It’s a smaller unit of volume than a cubic yard. Since each side of a cubic yard is three times larger, it contains 27 individual cubic feet.
Cubic Yard to Cubic Feet Formula
To convert cubic yards into cubic feet, use this formula:
Cubic Feet = Cubic Yards × 27
Examples
- 1 cubic yard = 27 cubic feet
- 2 cubic yards = 54 cubic feet
- 3 cubic yards = 81 cubic feet
- 5 cubic yards = 135 cubic feet
- 10 cubic yards = 270 cubic feet
Cubic Feet to Cubic Yard Formula
To convert cubic feet into cubic yards, use:
Cubic Yards = Cubic Feet ÷ 27
Examples
- 27 cubic feet = 1 cubic yard
- 54 cubic feet = 2 cubic yards
- 81 cubic feet = 3 cubic yards
- 108 cubic feet = 4 cubic yards
- 135 cubic feet = 5 cubic yards

Why This Conversion Matters
Many landscaping and construction suppliers sell materials by the cubic yard, while smaller bags are often labeled in cubic feet. Understanding the conversion helps you compare prices and determine how much material you actually need.
For example:
- Buying mulch for a flower bed
- Ordering topsoil for a lawn
- Purchasing gravel for a driveway
- Estimating concrete for a slab
- Filling raised garden beds
All these projects require volume calculations.
How to Calculate Cubic Feet
Before converting to cubic yards, calculate the total cubic feet.
Use this formula:
Length × Width × Height = Cubic Feet
All measurements should be in feet.
Example
A garden bed measures:
- Length: 10 feet
- Width: 4 feet
- Depth: 1 foot
Calculation:
10 × 4 × 1 = 40 cubic feet
Convert to cubic yards:
40 ÷ 27 = 1.48 cubic yards
Real-World Examples
Example 1: Mulch
A landscaping project requires 3 cubic yards of mulch.
3 × 27 = 81 cubic feet
Example 2: Topsoil
You have 108 cubic feet of soil.
108 ÷ 27 = 4 cubic yards
Example 3: Gravel
A driveway needs 162 cubic feet of gravel.
162 ÷ 27 = 6 cubic yards
Example 4: Concrete
A concrete slab measures:
- 12 feet long
- 10 feet wide
- 0.5 feet thick
Volume:
12 × 10 × 0.5 = 60 cubic feet
Convert:
60 ÷ 27 = 2.22 cubic yards
Common Materials Sold by the Cubic Yard
Bulk materials typically sold by cubic yard include:
- Mulch
- Topsoil
- Compost
- Gravel
- Sand
- Crushed stone
- River rock
- Concrete
- Fill dirt
- Wood chips
Knowing the cubic yard conversion makes ordering these materials much easier.
Cubic Feet vs. Cubic Yard
| Feature | Cubic Foot | Cubic Yard |
|---|---|---|
| Measurement | Volume | Volume |
| Size | Smaller | Larger |
| Equals | 1 cubic foot | 27 cubic feet |
| Typical Use | Small containers | Bulk materials |
Tips for Accurate Material Estimates
Follow these tips before placing an order:
- Measure carefully using feet.
- Include the depth of the area.
- Convert cubic feet to cubic yards by dividing by 27.
- Round up your order to allow for settling and waste.
- Double-check your calculations before purchasing.
Common Mistakes to Avoid
Confusing Square Feet and Cubic Feet
Square feet measure area, while cubic feet measure volume. Always include depth when calculating cubic measurements.
Mixing Units
Convert inches to feet before multiplying dimensions.
Ordering Too Little
Bulk materials often settle during transport. Ordering an extra 5–10% can prevent delays.
Expert Advice
Professional landscapers and contractors always calculate volume before ordering materials. Keeping the conversion factor of 27 cubic feet per cubic yard in mind makes estimating projects much easier and helps reduce waste and unnecessary costs.
Frequently Asked Questions
How many cubic feet are in one cubic yard?
One cubic yard contains 27 cubic feet.
What is the fastest way to convert cubic feet to cubic yards?
Divide the number of cubic feet by 27.
