Concrete Block Calculator
Calculate the number of concrete blocks needed for a wall of a given size.
How to use this calculator?
- Enter the height and width of the wall.
- Enter the height and width of the concrete blocks.
- Optionally, enter the price of a single block, allowing the calculator to estimate the total cost.
How to calculate the number of concrete blocks needed for a wall?
Firstly, calculate the wall area and block area. In both cases, simply multiply the height by the width.
Now, divide the wall area by the block area.
Now you should round up the value to ensure you have enough blocks. Use the "ceil" rounding for this purpose.
Wall area = 6 ft * 25 ft = 150 ft²
Block area = 16 in * 8 in = 128 in² = (128 / 144) ft² ≈ 0.89 ft²
Concrete blocks needed = 150 / 0.89 ≈ 168.54 ≈ 169
