About the Unit Converter

Unit conversion is a daily necessity in a world split between metric and imperial: recipes from another continent, fuel efficiency quotes in miles per gallon versus litres per 100 km, screen sizes in inches, body weight in kilograms versus stones, and data plans in megabytes.

This converter uses exact internationally-defined factors and handles the one category that doesn't convert by simple multiplication — temperature — with the correct offset formulas in both directions.

Frequently asked questions

How accurate are the conversions?

Conversion factors are the exact internationally defined values (for example 1 inch = 2.54 cm exactly, 1 pound = 0.45359237 kg exactly). Results are shown to a sensible number of digits.

Why does temperature need special handling?

Unlike length or weight, temperature scales have different zero points, not just different unit sizes. Converting °C to °F needs multiplication and addition — that's why “wind chill” and oven settings confuse everyone.

What's the difference between GB and GiB?

A gigabyte (GB) is 1,000,000,000 bytes; a gibibyte (GiB) is 1,073,741,824 bytes (1024³). That ~7% gap is why a “500 GB” drive shows as ~465 GiB in your operating system.
