Frequently asked questions

Does the file size converter use 1000 or 1024?

It uses decimal units, so 1 KB is 1,000 bytes, the same as most storage makers and operating systems like macOS.

Can I convert from Fahrenheit or feet?

Not yet. The temperature tool starts from Celsius and the length tool starts from meters.

Are the conversions exact?

They use standard definitions, such as 1 foot = 0.3048 m. Results are rounded for display.

Is anything sent to a server?

No. Every conversion runs in your browser.
