    Frequently Asked Questions

    Are these calculators suitable for Australian conditions?

    Yes. Every calculator on SiteCalc is built for Australia. We use metric measurements throughout, reference Australian standards where relevant (including the National Construction Code and AS/NZS standards), and use the terminology and product types that Australian tradies and hardware stores use.

    Do the calculators use metric or imperial units?

    All metric, all the time. Inputs are in millimetres, centimetres, or metres as appropriate. There are no feet, inches, or pounds on this site.

    Are the calculators free to use?

    Completely free. SiteCalc is supported by display advertising. You never need to create an account or enter any personal information to use any calculator.

    How accurate are the material estimates?

    Estimates are based on standard Australian industry formulas and include sensible wastage allowances where applicable. They are accurate enough for quoting and materials ordering, but always allow a small buffer — site conditions, cutting patterns, and mix variations can affect final quantities.

    What trade categories are covered?

    SiteCalc covers concrete, painting, tiling, carpentry, landscaping, electrical, plumbing and general site calculators. New calculators are added regularly.
