Temperature is not a simple ratio
Celsius and Fahrenheit scales start at different points, so the tool uses the offset formula rather than multiplying by a single factor.

Conversions use standard international definitions. Data sizes show both decimal and binary units because drives and operating systems label them differently.
The input and result stay in this browser tab. There is no upload step and no copy stored on a server. How local processing works.
The short version
How it works.
No installer, no sign-up, and no second app to open. The work happens in the browser you already have, using the file already on your device.
-
Pick a category
Choose length, weight, area, volume, temperature, speed, or digital storage.
-
Enter the value
Type the number and select the starting unit. The conversion updates as you type.
-
Read or swap the result
Copy the converted value, or use the swap button to convert in the opposite direction.
Fine print, without the runaround
Good to know.
Every tool has a boundary. These are the ones worth knowing before you start, so the result is not a surprise.
Storage units are ambiguous
A “gigabyte” in drive marketing usually means one billion bytes, while an operating system may show gibibytes. The converter labels both so the difference is visible.
How precise are the conversions?
The tool uses standard international definitions and displays a sensible number of decimal places. For engineering or legal work, confirm the required precision and rounding rules.
Can I convert cooking measurements?
Volume units include millilitres, litres, cups, tablespoons, and fluid ounces. Weight units include grams and ounces. Ingredient density still affects cup-to-gram conversions.
Does the converter work offline?
Yes. The conversion tables are part of the page and all calculations happen locally in your browser.
