The Elmer’s Concrete Calculator helps you quickly determine the amount of concrete needed for your project.
How to Use the Concrete Calculator:
To use this calculator, simply enter the length, width, depth of the area in feet and inches, the bag size in pounds, and the percentage of wastage. Click the ‘Calculate’ button, and the results will be displayed in the Results section.
Explanation of Calculation:
The total amount of concrete required is calculated by multiplying the area (length x width) with the depth (converted from inches to feet by dividing by 12), and then converting the result to cubic yards by dividing by 27. An additional calculation is made to include wastage by multiplying by a wastage factor (1 + wastage percentage). The total number of bags needed is calculated by converting the cubic yards to pounds (1 cubic yard = ~4050 pounds) and then dividing by the bag size.
Limitations:
This calculator assumes standard concrete weight and density, and is designed for general use. For special requirements, consult with a professional.
