What is the Concrete Calculator?
The Concrete Calculator is an online tool that calculate concrete volume for slabs, footings, and pads in cubic feet, yards, or metres.
What formula does the Concrete Calculator use?
This calculator uses the rule: Volume = length × width × depth. Enter your values in the tool above to apply it to your numbers.
How does the Concrete Calculator work?
Enter length, width, and depth. Volume = L × W × D. We show cubic feet, cubic yards (÷27), cubic metres, and approximate 80 lb bag count.
Formula Used
The equation below is what this calculator applies. Variable definitions follow when symbols are used.
Equation
