Construction & DIY Calculators

Whether you are getting a house built, retiling a bathroom or landscaping a garden, the hardest part is often estimating how much material to order so you are not left short or paying for a surplus. This cluster covers the everyday building maths, from the Concrete and Tile calculators that size up exactly what a job needs (with a waste allowance) to the Square Footage and Roofing calculators that handle areas and pitched roofs. The Gravel, Mulch and Stair calculators take care of the rest of a typical project.

For Indian buyers and builders, land and plot sizes bring their own headache because traditional units differ from one state to the next. The Area Converter handles this directly, converting between local units like bigha, biswa, katha, gaj, guntha, ground, cent and chatak and standard units such as square feet, square metres and acres. Since a bigha is not the same size everywhere, it supports the common state variants for UP, Bihar, MP, Rajasthan, Punjab and more so your conversions match local usage.
