What can I calculate quantities for?

Enter the dimensions of the work and get the amount to buy. Each calculator stops at the purchase unit — whole blocks, cubic metres of bedding mortar, complete boxes of tile — instead of breaking the mix down into cement and sand, because that is the number you order with.

Which reference tables are here?

The figures people look up on site, on one page and ready to copy. Every table states the standard it follows and the tolerance that applies, so a value can be quoted with its source rather than trusted blindly.

Rebar weight table

Diameter, area, kilograms per metre and per 6 m and 12 m bar, for every reinforcing bar size.

What can I convert?

Convert between the units on the drawing, the units the supplier quotes and the units the code uses. That includes trade units such as arrobas, cement bags and tipper loads, and the three ways concrete strength is written: psi, MPa and kg/cm².

From a quantity to a budget

These tools settle one quantity. Geztio builds the whole budget: chapters, unit-price analysis with real output rates, overhead and profit, and an Excel export.
