How to Convert Units Online
Select a category from the tabs at the top — Length, Weight, Temperature, Speed, Area, Volume, Time, or Data. Enter a value in the left field, choose your “from” unit and “to” unit, and the conversion happens instantly. Click the swap button (⇄) to quickly reverse the conversion direction. Each category includes quick reference conversions at the bottom for common unit pairs.
Supported Conversions
Our unit converter covers 8 categories with dozens of unit combinations. Length conversions include kilometers, miles, meters, feet, inches, and more. Weight covers kilograms, pounds, ounces, and stones. Temperature handles Celsius, Fahrenheit, and Kelvin with the correct formulas (not just multiplication). Speed converts between km/h, mph, m/s, and knots. Area, volume, time, and data storage round out the full set of everyday conversions.
Why Use a Unit Converter?
Whether you’re cooking with a recipe from another country, traveling abroad, working on a science project, or comparing product specifications, unit conversions come up constantly. Temperature is especially tricky — converting Celsius to Fahrenheit isn’t a simple multiplication. Our tool handles the math correctly every time, showing you both the result and the conversion formula for reference.
Frequently Asked Questions
How accurate are the conversions?
All conversions use precise conversion factors. Results are displayed with appropriate decimal precision — more digits for small values, fewer for large numbers.
Does the data converter use 1000 or 1024?
Our data converter uses binary units (1 KB = 1024 bytes), which is the standard used by operating systems and storage devices. Some contexts use decimal units (1 KB = 1000 bytes), so be aware of the difference.
Can I convert between different categories?
No — you can only convert between units within the same category (e.g., length to length). Converting between categories (like weight to volume) depends on the material’s density and requires additional information.
