The Unit Converter is an all-in-one conversion tool that handles length, weight, temperature, and data size on a single page. Use the tabs to switch between categories, enter your value, select source and target units, and see the result update in real time as you type. Whether you need to convert kilometers to miles, kilograms to pounds, Celsius to Fahrenheit, or megabytes to gigabytes, this tool covers it all with standard conversion factors. Each category supports both metric and imperial units. All calculations run entirely in your browser — nothing is sent to any server, ensuring complete privacy.
About Unit Converter
The Unit Converter combines four essential conversion categories into a single convenient page: Length (km, m, cm, mm, miles, yards, feet, inches), Weight (kg, g, mg, lb, oz), Temperature (Celsius, Fahrenheit, Kelvin), and Data Size (bytes, KB, MB, GB, TB, PB with binary or decimal calculation). Each category uses the same internationally recognized conversion factors as our dedicated converter tools.
The tabbed interface lets you switch instantly between categories without loading a new page. Results update in real time as you type, providing immediate feedback. For data sizes, you can toggle between binary (1024-based, used by operating systems) and decimal (1000-based, used by storage manufacturers) calculations. You can also access each category through its dedicated tool: Length Converter, Weight Converter, Temperature Converter, and Data Size Converter.

Technical Details
Each conversion category uses a base-unit approach: values are first converted to a base unit (meters for length, kilograms for weight, Celsius for temperature, bytes for data size) and then converted to the target unit. This ensures consistency and minimizes rounding errors. Temperature uses the standard formulas: °F = °C × 9/5 + 32 and K = °C + 273.15. Data size supports both binary prefixes (1 KB = 1024 bytes) and decimal prefixes (1 KB = 1000 bytes). All calculations run in JavaScript within your browser with no external API calls.
Conclusion
