Common questions
Why is Fahrenheit conversion not a simple multiplier?
Celsius and Fahrenheit have different zero points as well as different scale sizes, so the conversion includes an offset.
What is absolute zero?
Absolute zero is 0 K, equal to −273.15°C or −459.67°F.
Can I convert Kelvin?
Yes. Kelvin is available as both a source and target scale.
