Volume Calculation

Concrete Volume:

When planning a concrete project, knowing the exact volume of concrete required is crucial. Whether you’re pouring a slab, footing, patio, or foundation, our Concrete Volume Calculator helps you estimate the volume in cubic yards, cubic feet, and cubic meters quickly and easily.

How to Calculate Concrete Volume

You simply need three measurements:

Length (in feet)
Width (in feet)
Depth/Thickness (in inches)

Then apply the following formulas to get concrete volume in different units.

How to Calculate Concrete Volume?

Formula to calculate Concrete Volume in Cubic Feet

Formula

$\text{Concrete Volume (cubic feet)} = \text{Length (ft)} \times \text{Width (ft)} \times \frac{\text{Depth (in)}}{12}$

Formula to calculate Concrete Volume in Cubic Yards

Formula

$\text{Concrete Volume (cubic yards)} = \frac{ \text{Length (ft)} \times \text{Width (ft)} \times \text{Depth (in)} }{ 27 \times 12 }$

Note: 1 cubic yard = 27 cubic feet

Formula to calculate Concrete Volume in Cubic Meters

Formula

$\text{Concrete Volume (cubic meters)} = \text{Length (ft)} \times \text{Width (ft)} \times \frac{ \text{Depth (in)} }{12} \times 0.0283168$

Note: 1 cubic foot = 0.0283168 cubic meters

Example Calculation

Let’s calculate for a slab that is:

Length = 15 feet
Width = 12 feet
Depth/Thickness = 6 inches

Step 1: Calculate Volume in Cubic Feet

$\text{Volume (ft³)} = 15 \times 12 \times \frac{6}{12} = 15 \times 12 \times 0.5 = 90 \, \text{cubic feet}$

Step 2: Calculate Volume in Cubic Yards

$\text{Volume (yd³)} = \frac{15 \times 12 \times 6}{27 \times 12} = \frac{1080}{324} = 3.33 \, \text{cubic yards}$

Step 3: Calculate Volume in Cubic Meters

$\text{Volume (m³)} = 15 \times 12 \times 0.5 \times 0.0283168 = 90 \times 0.0283168 = 2.5485 \, \text{cubic meters}$

Conclusion

With our Concrete Volume Calculator, you can quickly estimate the required volume of concrete in yards, feet, and meters — making your construction planning easier and more precise.

Always consider ordering slightly more concrete (5%–10% extra) to account for spillage or measurement errors.

Frequently Asked Questions (FAQs) about Concrete Volume

1. Why do I need to know the volume of concrete?

Knowing the concrete volume ensures you order the right amount — avoiding costly shortages or wastage.

2. What units does the Concrete Volume Calculator use?

Our calculator returns the result in cubic yards, cubic feet, and cubic meters — covering both US and metric systems.

3. How accurate is the calculator?

The calculator is highly accurate as long as you enter correct length, width, and depth. Always double-check your measurements.

4. How much extra concrete should I order?

It is recommended to order 5% to 10% extra concrete to account for spillage, over-excavation, or slight measurement changes.

5. Can this calculator work for circular slabs or footings?

This calculator is best for rectangular or square areas. For circular slabs, you would use a different formula (I can give that too if you want!).
