- Width (in feet)
- Depth (in inches)
- Cost per cubic yard
2. Automatic Unit Conversion
The calculator automatically converts depth from inches to feet and volume into cubic yards.
3. Accurate Volume Calculation
It calculates both cubic feet and cubic yards for better understanding.
4. Cost Estimation
Enter the cost per cubic yard to instantly calculate total project cost.
5. Instant Results
Results are displayed immediately after clicking the calculate button.
6. Reset Option
Quickly clear inputs and start a new calculation anytime.
How to Use the Concrete Calculator
Using this calculator is simple and requires just a few steps:
Step 1: Enter Length
Input the length of the area in feet.
Step 2: Enter Width
Provide the width in feet.
Step 3: Enter Depth
Enter the depth in inches (this will be automatically converted).
Step 4: Enter Cost (Optional)
Add the cost per cubic yard of concrete. If you don’t know it, you can leave it blank.
Step 5: Click Calculate
Press the “Calculate” button to see results instantly.
Step 6: View Results
The tool will display:
- Total volume in cubic feet
- Total volume in cubic yards
- Estimated total cost
Example Calculation
Let’s understand how the calculator works with a practical example:
Project Details:
- Length = 20 feet
- Width = 10 feet
- Depth = 6 inches
- Cost per cubic yard = $120
Step 1: Convert Depth
6 inches = 0.5 feet
Step 2: Calculate Cubic Feet
Volume = Length × Width × Depth
= 20 × 10 × 0.5
= 100 cubic feet
Step 3: Convert to Cubic Yards
1 cubic yard = 27 cubic feet
100 ÷ 27 = 3.70 cubic yards
Step 4: Calculate Cost
3.70 × 120 = $444
Final Result:
- Cubic Feet: 100
- Cubic Yards: 3.70
- Estimated Cost: $444
This example shows how quickly and accurately the calculator works.
