About

ForemanCalc is a free set of construction and DIY calculators for everyday building jobs: working out tiles, bricks, gravel, concrete, rafters, board feet and more. Enter your measurements in imperial or metric and get the quantity, the weight and the cost, with the formula and a worked example shown on every page.

Why it exists

Most material questions come down to simple maths, but the formulas are easy to get wrong and most online tools hide how they reach a number. ForemanCalc shows the method on every page, so you can check the result yourself and trust it before you order.

How the numbers are checked

Every calculator is built from a standard formula and tested against known examples before it goes live. Material weights and other reference figures are approximate and are labelled as estimates, because they vary with the product and conditions. See the Methodology page for how this works.

Who runs it

ForemanCalc is built and maintained by Muhammad Muheet, a web developer who checks every calculator against published engineering and trade references before it goes live and updates the numbers when standards or prices change.
