Engineering calculators
Free tools for site and office. Load calculators follow IS 875 (Parts 1 & 2) and show every step.
Handheld-style scientific calculator with fractions, ENG notation, memory and history. Pops out into its own floating window.
Open calculator → Wall loadBrick, fly-ash, AAC or block wall with plaster and openings. Gives the line load on the beam in kN/m, plus parapets.
Calculate → Floor loadSlab, floor finish, ceiling plaster, partition allowance and imposed load by occupancy. DL, LL and 1.5(DL+LL).
Calculate → Roof loadSlab, weathering course and waterproofing, with imposed load for accessible, non-accessible and sloping roofs.
