UnitFormula - The unit converter that actually explains the conversion

by•
Most converters give you "1 lb = 0.4536 kg" and stop. UnitFormula gives you 2,000 words of history, industry context, worked examples, common mistakes, and 7 FAQs — for every one of 187 conversion pairs. Plus 44 interactive calculators (electrical, finance, health, construction, cooking) and 30 educational guides. All free, no login required. Built with Next.js 15, 347 statically-generated pages, 4 JSON-LD schemas per page.

Hey everyone! I'm Abdilahi, the developer behind UnitFormula. I built this because every unit converter I found online gave me "1 lb = 0.4536 kg" and stopped there. I wanted to know why that specific number, where it came from, and when the conversion actually matters in practice. So I built UnitFormula with 2,000+ words of expert content per conversion — covering history, industry context, worked examples, common mistakes, and FAQs. Every page has 4 structured data schemas for search engines, and every calculator handles real-world complexity (like 3-phase AC power with power factor, not just simple multiplication). What's live right now: - 187 conversion pairs across 18 categories - 44 interactive calculators (electrical, finance, health, construction, cooking, math) - 30 educational guides - 50 long-tail value pages for the most-searched specific conversions The whole thing is free, no login required, no ads (yet). Built with Next.js 15, fully statically generated, sub-second load times. I'd love feedback on: 1. Are there conversions or calculators you wish existed but can't find online? 2. How does the content depth feel — useful or overwhelming? 3. Any categories I'm missing? Thanks for checking it out!
