AAC Block Calculator: Estimate block quantity based on square meters
How many lightweight concrete blocks are needed per square meter?
For constructing walls using standard-sized lightweight concrete blocks (20 x 60 cm). Approximately 8.33 bricks will be needed per square meter. Regardless of the thickness (7.5, 10, or 20 cm), the cross-sectional area for construction is the same.
Recommendations: It is recommended to order an extra 5-10% to cover trimming and on-site breakage/damage, ensuring work is not interrupted.
Detailed calculation method (Step-by-Step)
How to calculate the number of lightweight bricks you need yourself.
- Convert units to centimeters: One square meter is equal to 10,000 square centimeters (100 x 100 cm).
- Find the cross-sectional area of the brick: Standard size lightweight concrete blocks are 20 cm wide and 60 cm long.
- formula: 20 x 60 = 1,200 square centimeters/block
- Divide them together: Divide the area of the vertical wall by the area of the brick.
formula: 10,000 ÷ 1,200 = 8.33 blocks
