Most calculators use US units (cubic yards, 80lb bags). MixCalc uses what Indian builders actually work with: 50kg bags, cft/m³, M10–M30 grades, and ₹ pricing. 6 free tools: slab, cement bag conversion, mix ratio, sand/aggregate, plastering, and brick calculators. Every result shows its formula and exports as a PDF for your mason. No login. No ads. Built because I couldn't find one that spoke in Indian units.

Hey Product Hunt 👋 I built MixCalc because every time I needed to estimate cement, sand, or aggregate for a small project, I'd end up either doing manual math with mix ratios, or using a calculator built around US units (cubic yards, 80lb bags) that didn't map to how construction actually works in India — 50kg bags, cft, ₹ pricing. So I built the version I actually wanted: 6 free calculators (slab, cement bag conversion, mix ratio, sand/aggregate, plastering, bricks), each showing its formula so you're not just trusting a black-box number, plus a PDF export you can hand straight to your mason or contractor on-site. No login, no ads, no paywall — just the tools. Would genuinely love feedback, especially if you've worked in construction/civil engineering in India and can tell me if the mix ratios or assumptions need tightening anywhere. And if there's a calculator you wish existed that isn't here yet, tell me — that's exactly how the next one gets picked.

Finally someone built this for our actual units, the cft and 50kg bag conversions save me real time on site. Love that the PDF export goes straight to the mason without any signup nonsense.
