Transparent formulas, honest limitations.
We calculate geometric quantities using one internal metric measurement system. UK and USA values are converted for display. Pack sizes, product yield, density and coverage remain editable because real materials differ.
Our estimates cannot replace a site survey or professional structural advice. See calculation methods and sources.
