If you’re working with landscaping, construction, gardening, or bulk materials, you may need to know how many cubic feet equal 1 yard.
The answer is simple:
1 cubic yard = 27 cubic feet
A cubic yard is a unit of volume measuring a space that is:
3 feet long × 3 feet wide × 3 feet high
Because:
3 × 3 × 3 = 27
one cubic yard contains exactly 27 cubic feet.
This conversion is especially useful when buying or calculating quantities of soil, mulch, gravel, sand, concrete, compost, and other materials.
For example, if you have 4 cubic yards of mulch, you can convert it to cubic feet by multiplying:
4 × 27 = 108 cubic feet
So, 4 cubic yards equals 108 cubic feet.
Quick Answer: How Many Cubic Feet Are in 1 Yard?
One cubic yard equals exactly 27 cubic feet.
The formula is:
1 cubic yard = 27 cubic feet
This works because a cubic yard is three-dimensional.
One yard equals 3 feet:
3 feet × 3 feet × 3 feet = 27 cubic feet
Therefore:
1 yd³ = 27 ft³
Remember that this applies to a cubic yard, not simply one linear yard.
A linear yard measures length, while a cubic yard measures volume.
What Is a Cubic Yard?
A cubic yard is a unit used to measure volume.
Imagine a cube that measures:
- 3 feet long
- 3 feet wide
- 3 feet high
The volume is:
3 × 3 × 3 = 27 cubic feet
That entire space equals 1 cubic yard.
Cubic yards are commonly used for large quantities of bulk materials because they are more convenient than using individual cubic feet.
You may see materials sold by the cubic yard at:
- Landscaping suppliers
- Garden centers
- Construction suppliers
- Concrete companies
- Gravel yards
- Soil suppliers
What Is a Cubic Foot?
A cubic foot is also a unit of volume.
One cubic foot represents a cube that measures:
1 foot × 1 foot × 1 foot
Therefore:
1 × 1 × 1 = 1 cubic foot
Cubic feet are useful for measuring smaller volumes.
For example, storage containers, appliances, refrigerators, boxes, and smaller amounts of materials may be described in cubic feet.
When dealing with large outdoor projects, however, cubic yards are often more convenient.
How Do You Convert Cubic Yards to Cubic Feet?
The conversion is very easy.
Formula
Cubic feet = Cubic yards × 27
For example, suppose you have 6 cubic yards of soil.
Multiply:
6 × 27 = 162 cubic feet
Therefore:
6 cubic yards = 162 cubic feet
This formula works for any number of cubic yards.

The relationship is always the same:
1 cubic yard = 27 cubic feet
How Do You Convert Cubic Feet to Cubic Yards?
You can also convert in the opposite direction.
Formula
Cubic yards = Cubic feet ÷ 27
For example, suppose you have 135 cubic feet of mulch.
Calculate:
135 ÷ 27 = 5 cubic yards
Therefore:
135 cubic feet = 5 cubic yards
This is useful when you know the volume required in cubic feet but the supplier sells the material by cubic yards.
Why Is 1 Cubic Yard Equal to 27 Cubic Feet?
The reason comes from the dimensions of a cube.
One yard equals:
3 feet
A cubic yard has three dimensions:
3 feet × 3 feet × 3 feet
Multiply:
3 × 3 × 3 = 27
Therefore:
1 cubic yard = 27 cubic feet
This is different from converting linear measurements.
For example:
1 yard = 3 feet
But:
1 square yard = 9 square feet
And:
1 cubic yard = 27 cubic feet
The number increases because each additional dimension multiplies the conversion.
Linear Yards vs. Square Yards vs. Cubic Yards
Understanding the difference between these units can prevent measurement mistakes.
| Measurement | What It Measures | Conversion |
| 1 linear yard | Length | 3 feet |
| 1 square yard | Area | 9 square feet |
| 1 cubic yard | Volume | 27 cubic feet |
Linear Yard
Measures one dimension.
1 yard = 3 feet
Square Yard
Measures two dimensions.
1 square yard = 3 × 3 = 9 square feet
Cubic Yard
Measures three dimensions.
1 cubic yard = 3 × 3 × 3 = 27 cubic feet
The word cubic is important because it tells you that you’re measuring volume.
How Many Cubic Feet Are in a Yard of Soil?
If someone says they have 1 cubic yard of soil, that equals:
27 cubic feet
For example:
- 2 cubic yards = 54 cubic feet
- 3 cubic yards = 81 cubic feet
- 5 cubic yards = 135 cubic feet
The weight of the soil can vary considerably depending on moisture, soil type, and composition, but the volume conversion remains exactly the same.
How Many Cubic Feet Are in a Yard of Mulch?
One cubic yard of mulch contains exactly:
27 cubic feet
If you purchase 3 cubic yards:
3 × 27 = 81 cubic feet
So 3 cubic yards of mulch equals 81 cubic feet.
However, mulch coverage depends on how thickly you spread it.
For example, one cubic yard can cover a larger area when spread 1 inch deep than when spread 4 inches deep.
How Many Cubic Feet Are in a Yard of Gravel?
A cubic yard of gravel also equals:
27 cubic feet
The conversion does not change based on the material.
Whether you’re measuring:
- Gravel
- Sand
- Soil
- Mulch
- Compost
- Concrete
one cubic yard always contains 27 cubic feet.
What changes is the material’s weight and how much surface area it covers at a particular depth.
How Many Cubic Feet Are in a Yard of Concrete?
One cubic yard of concrete equals:
27 cubic feet
Concrete is commonly ordered by cubic yards because large slabs and foundations can require significant volumes.
For example:
2 cubic yards = 54 cubic feet
10 cubic yards = 270 cubic feet
The actual amount required for a project depends on the slab’s length, width, and thickness.
How to Calculate Cubic Yards for a Project
If you need to determine how many cubic yards of material to order, start by calculating the volume in cubic feet.
The basic formula is:
Length × Width × Depth = Cubic Feet
Make sure all measurements are in feet.
Then convert cubic feet to cubic yards:
Cubic Feet ÷ 27 = Cubic Yards
Example
Suppose you have an area that is:
- 20 feet long
- 10 feet wide
- 0.25 feet deep
First calculate the volume:
20 × 10 × 0.25 = 50 cubic feet
Then convert:
50 ÷ 27 = 1.85 cubic yards
You would need approximately 1.85 cubic yards of material before accounting for waste, settling, or additional material requirements.
How Many Cubic Yards Do You Need for Mulch?
Suppose your garden is:
30 feet long × 20 feet wide
The area is:
30 × 20 = 600 square feet
You want mulch 3 inches deep.
Convert 3 inches to feet:
3 ÷ 12 = 0.25 feet
Calculate the volume:
600 × 0.25 = 150 cubic feet
Now convert to cubic yards:
150 ÷ 27 ≈ 5.56 cubic yards
You would need approximately 5.6 cubic yards of mulch based on the mathematical volume.
In a real project, you may want to order a little extra to account for settling and uneven application.
How Many Cubic Feet Does 1 Cubic Yard Cover?
A cubic yard contains 27 cubic feet, but the square footage it covers depends on depth.
For example:
At 1 Foot Deep
27 ÷ 1 = 27 square feet
At 6 Inches Deep
Six inches equals 0.5 feet:
27 ÷ 0.5 = 54 square feet
At 3 Inches Deep
Three inches equals 0.25 feet:
27 ÷ 0.25 = 108 square feet
At 2 Inches Deep
Two inches equals approximately 0.167 feet:
27 ÷ 0.167 ≈ 162 square feet
At 1 Inch Deep
One inch equals approximately 0.0833 feet:
27 ÷ 0.0833 ≈ 324 square feet
This demonstrates how depth affects coverage.

How Many Bags Equal One Cubic Yard?
The answer depends on the size of each bag.
For example, suppose a bag contains 2 cubic feet of material.
One cubic yard contains 27 cubic feet:
27 ÷ 2 = 13.5 bags
Therefore, you would need approximately 14 two-cubic-foot bags to equal one cubic yard.
If bags contain 1 cubic foot each:
27 ÷ 1 = 27 bags
If bags contain 1.5 cubic feet:
27 ÷ 1.5 = 18 bags
Always check the bag’s stated volume.
Why Buy Bulk Material by the Cubic Yard?
For large projects, buying bulk materials by the cubic yard can be more convenient and economical than purchasing many individual bags.
Bulk delivery can be useful for:
- Large gardens

For small projects, bags may be easier to transport and store.
The best choice depends on the size of your project, material price, delivery fees, and available storage space.
Common Mistakes When Converting Cubic Yards
Mistake 1: Using 3 Instead of 27
Some people multiply cubic yards by 3 because one yard equals 3 feet.
That’s incorrect for volume.
You must multiply by:
3 × 3 × 3 = 27
Mistake 2: Confusing Square and Cubic Yards
One square yard equals 9 square feet.
One cubic yard equals 27 cubic feet.
These are different measurements.
Mistake 3: Forgetting to Convert Inches
If project depth is given in inches, convert it to feet before calculating cubic feet.
Mistake 4: Ignoring Material Settling
Some materials settle after being installed.
Mistake 5: Ordering the Exact Mathematical Amount
Uneven surfaces and installation losses can make the theoretical amount slightly different from actual requirements.
Tips for Accurate Material Estimates
Follow these steps before ordering bulk material:
Step 1: Measure Length
Measure the area’s length in feet.
Step 2: Measure Width
Measure the width in feet.
Step 3: Determine Depth
Measure the required material depth.
Step 4: Convert Inches to Feet
Divide inches by 12.
Step 5: Calculate Cubic Feet
Multiply:
Length × Width × Depth
Step 6: Convert to Cubic Yards
Divide:
Cubic Feet ÷ 27
Step 7: Add an Appropriate Allowance
Consider settling, uneven ground, and installation waste before placing your order.
Real-World Example: Calculating Soil
Imagine you want to fill a garden bed measuring:
12 feet × 8 feet
You want soil 6 inches deep.
Convert 6 inches:
6 ÷ 12 = 0.5 feet
Calculate volume:
12 × 8 × 0.5 = 48 cubic feet
Convert to cubic yards:
48 ÷ 27 ≈ 1.78 cubic yards
So the project requires approximately 1.78 cubic yards of soil.
Depending on the supplier’s ordering increments, you may need to purchase 2 cubic yards.
Real-World Example: Gravel Driveway
Suppose a driveway is:
- 40 feet long
- 10 feet wide
- 4 inches deep
Convert depth:
4 ÷ 12 = 0.333 feet
Calculate:
40 × 10 × 0.333 ≈ 133.2 cubic feet
Convert:
133.2 ÷ 27 ≈ 4.93 cubic yards
So you need approximately 4.9 cubic yards of gravel based on the calculated volume.
Actual requirements may vary depending on the existing base and compaction.
