Frequently asked questions
What is a construction calculator?
A construction calculator turns site and design inputs into quantities or checks, such as concrete volume from slab dimensions, rebar weight from bar length and diameter, or cable size from load current and length. These calculators use published formulas and show the formula and assumptions on each page.
Are these engineering calculators free?
Yes. Every calculator on this page is free to use without an account. You can copy the results or a link to your calculation, and you can ask for the calculation to be emailed to you.
Can I use the results in a design or a contract?
Treat them as preliminary estimates. Structural, MEP and temporary works results must be checked by a qualified engineer against the governing code and project specification before they are used in design, procurement or contracts.
Do the calculators work in metric and imperial units?
The quantity, structural, MEP and finishing calculators with unit-dependent inputs have a metric and imperial switch. Your choice is remembered in your browser. Some calculators are available in Arabic as well.
