Guide
Formula
°F = °C × 9/5 + 32
Celsius and Fahrenheit use different step sizes and different zero points, so the conversion needs both scaling and an offset. For example, 0 °C equals 32 °F and 100 °C equals 212 °F.
Note : For absolute temperatures, the catalogue also enforces the physical lower limit of 0 kelvin.
Example : 20 °C
