Construction calculators with cited sources
These masonry and concrete block calculators trace every number to a named source and show it right next to the result, so the contractor pricing a job and the engineer checking the takeoff see the same evidence.
Features
- Every constant is cited. Behind each result is a sourced value: the figure, its unit, and the standard it comes from, shown inline so you can check it.
- Two methods, never blended. Where an industry table and a geometric derivation disagree, we report both and name each, instead of averaging them into a number nobody can trace. why published calculators disagree by up to 20×
- Free, private, no sign-up. Every calculator runs in your browser. The values you enter are never stored or sent, and there is no account to create.
Comments
The cited-sources approach is what sets this apart. Most construction calculators hand you a number and ask for blind trust, which is exactly the wrong thing when you are pricing a job or defending a takeoff to an engineer. Showing the figure, its unit and the source right next to the result makes disputes much easier. Do you plan to cover more materials beyond masonry and concrete block, like lumber or steel quantities?
