One Tool for Every Everyday Unit Conversion
Whether you are following a recipe that uses cups when you only own a kitchen scale, shipping a parcel that needs dimensions in inches rather than centimetres, or decoding a cloud-provider pricing sheet that lists data transfer in gigabits — this Unit Converter covers the ground with four categories and dozens of units, updated in real time as you type.
Supported Categories
- Length — millimetres, centimetres, metres, kilometres, inches, feet, yards, miles, and nautical miles. Useful for travel distances, screen sizes, woodworking plans, and architectural drawings.
- Weight — milligrams, grams, kilograms, metric tons, ounces, pounds, and stone. Covers cooking, shipping, body weight tracking, and pharmaceutical dosing.
- Temperature — Celsius, Fahrenheit, and Kelvin. Temperature conversion is non-linear, so the tool handles the full formula (not just a factor) for every direction. Particularly handy for oven temperatures, weather comparisons, and scientific calculations.
- Data Size — bytes, kilobytes, megabytes, gigabytes, terabytes, petabytes, and the bit variants (kilobits, megabits, gigabits). Uses the binary (1 KB = 1024 B) standard that matches how Windows, macOS, and Linux actually report storage.
How to Use It
Pick a category from the dropdown at the top, then choose your source unit (From) and target
unit (To) using the two selectors. Type a number into the input field and the converted value
appears immediately in the result panel — no button press required.
Hit the swap button (⇄) between the unit selectors to reverse the direction in one click.
The Copy button copies a full equation (e.g. 100 cm = 39.3701 in) to your
clipboard, ready to paste into a document, email, or spreadsheet.

Common Use Cases
Developers reach for the data-size category when translating between network speeds (megabits) and storage sizes (megabytes), or checking whether a file will fit within an S3 storage tier. Travellers use the length and temperature categories when crossing between countries that use different measurement systems. Fitness enthusiasts convert body weight from kilograms to pounds and vice versa to compare with apps that default to a different unit. Scientists and engineers frequently need Kelvin for thermodynamic calculations, while chefs need Fahrenheit when following American recipes on a gas mark oven.
Privacy
The converter runs entirely in your browser with no server calls of any kind. Your numbers never leave your device, which means it is safe to use with confidential figures such as proprietary measurements, medical values, or internal capacity planning data. It also works offline once the page is cached.
Frequently Asked Questions
How do I convert Celsius to Fahrenheit?↓
Select the Temperature category, choose Celsius as the "From" unit and Fahrenheit as the "To" unit, then type your value. The formula used internally is °F = (°C × 9/5) + 32, so 100 °C converts to 212 °F.
Does this tool support metric and imperial units?↓
Yes. For length you can convert between millimetres, centimetres, metres, kilometres, inches, feet, yards, miles, and nautical miles — mixing metric and imperial freely. For weight, both the metric system (mg, g, kg, metric ton) and the imperial/US system (oz, lb, stone) are included.
Is 1 kilobyte (KB) equal to 1000 bytes or 1024 bytes?↓
This converter uses the binary (IEC) convention where 1 KB = 1024 bytes, 1 MB = 1024 KB, and so on. This matches how most operating systems report file and storage sizes. The SI convention (1 KB = 1000 bytes) is used by hard-drive manufacturers but is less common in software contexts.
Can I convert between miles and kilometres?↓
Yes. Select the Length category, pick Miles as the "From" unit and Kilometres as the "To" unit. One mile is exactly 1.60934 km, so 26.2 miles (a marathon) is approximately 42.16 km.
Does this converter store or transmit my data?↓
No. Every calculation runs entirely inside your browser using JavaScript. No data is sent to any server, and nothing is logged or stored. It works offline once the page has loaded.
