Frequently asked questions

How do unit conversions work?

Most conversions multiply by a fixed factor, such as 1 mile equalling 1.609344 kilometres or 1 pound equalling 0.45359237 kilograms. Temperature is the exception: Celsius to Fahrenheit multiplies by 9/5 and then adds 32, because the two scales start from different zero points.

Which units can it convert?

Common units of length, weight, temperature, volume, area, speed, time and pressure, including mixed inputs like 5 feet 6 inches. If a request cannot be converted, such as kilograms to metres, the AI is told to explain why rather than guess.

Is my question sent to a server?

Yes. Your question goes to our server, which passes it to an AI language model to work out the answer. The question itself is not saved, and the tool is free to use with no sign-up.

Are the results always right?

The answers come from an AI model, so they are usually right for everyday conversions but can slip on unusual ones. Check the conversion factor shown in the details, and double-check anything important, like medication doses or engineering specs.
