Hi everyone, I’m the solo maker behind OmexCalculator. I started it because most calculator sites give you a number and nothing else. You never find out how it was worked out, and many ignore that rules and units differ by country. So every calculator here has a guide that explains the formula, and some are built for a specific country (the US, India and others) so the results actually fit where you live. Right now: Money calculators use USD, and a multi-currency selector is on the roadmap Every page suggests related and popular calculators The guides section keeps growing alongside the tools I’m still adding calculators, so I’d love to hear which ones you’d use most and what’s missing. Any feedback on accuracy, design or speed is welcome, and I’m happy to answer questions about how it’s built. Thanks for checking it out!
