Concrete Block / CMU Calculator — free online calculator.
Formula
- Concrete Block / CMU Calculator calculates its result from Length, Block Width, Joint, Height, Block Height, Blocks, Wastage. It uses the formula Blocks per row = ceil(Length / (Block Width + Joint)); Rows = ceil(Height / (Block Height + Joint)); Total = ceil(Blocks × Rows × (1 + Wastage%)). Change any input to recalculate the result instantly.
- The main inputs are Length, Block Width, Joint, Height, Block Height, Blocks, Wastage. Enter them in the units and format shown in the calculator.
- Keep measurements and project assumptions consistent before comparing or combining values.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Concrete Block / CMU
- Length: 2
- Block Width: 3
- Joint: 4
- Height: 5
- Block Height: 6
- Blocks: 7
- Wastage: 16
Using Length = 2, Block Width = 3, Joint = 4, Height = 5, Block Height = 6, Blocks = 7, Wastage = 16, the calculated result is 9.
