Frequently asked questions

What do kB, MB, GB mean?

This converter uses the decimal system (1 MB = 1000 kB), the standard used by drive makers and data plans. For the binary system (1 MiB = 1024 KiB) values differ slightly.

How do I convert temperatures?

Temperature does not use simple factors: Celsius, Fahrenheit and Kelvin have their own formulas. The tool applies the correct formulas automatically.
