Free Online Unit Converter – 13 Categories, Instant Results
This free unit converter handles 13 measurement categories — length, weight, temperature, area, volume, speed, pressure, energy, digital data, fuel efficiency, time, cooking, and the Indian numbering system (Lakh, Crore, Arab) — without any login, subscription, or app download. Whether you're a student in Bengaluru solving physics problems, a chef in London scaling recipes, or an engineer in the USA working with mixed imperial and metric systems, you get instant, accurate results right in your browser.
India-Specific Measurement Units Included
Unlike generic converters, this tool includes traditional Indian units used every day in real estate, commodity markets, finance and kitchens: Bigha, Katha and Guntha for land area (note: Bigha varies by state — the tool uses the common UP/Bihar/Rajasthan value; always verify locally), Tola, Ser and Maund for weight, a Lakh/Crore/Arab Number System category for finance, and common Indian cooking measures. High-demand conversions for users in the UAE (sq ft to sq m), Canada (Celsius to Fahrenheit), Australia (km to miles) and Germany (kg to pounds) are all covered instantly.
How to Use the Converter
Pick your category from the 13 icons, choose the From and To units, type your value, and the result appears immediately — no Calculate button needed. The full conversion table shows every unit in that category at once, so you can compare values side by side. Tap the swap button to reverse the conversion, copy the result with one click, and check your recent conversions in the history log.
Accurate Formulas, Always Visible
Every result shows the underlying formula so you can verify the maths and learn the conversion factor — ideal for students preparing for competitive exams like JEE, NEET, UPSC and SSC, or professionals working across the US, UK, Australian and Indian measurement systems.
