Frequently asked questions
Are binary and decimal storage units different?
Yes. A kilobyte is 1,000 bytes while a kibibyte is 1,024 bytes. Select the explicit unit rather than assuming the same multiplier.
Why is temperature conversion different?
Absolute Celsius, Fahrenheit and Kelvin conversions include an offset. These converters operate on temperatures, rather than temperature differences.
