How to convert Celsius to Fahrenheit
To convert Celsius to Fahrenheit, multiply by 9/5 (1.8) and add 32. Unlike length or weight, temperature scales have a different zero point, so there is an offset of 32 degrees as well as a scaling factor.
°F = °C × 9/5 + 32
For example, 20°C × 1.8 + 32 = 68°F. Water freezes at 0°C (32°F) and boils at 100°C (212°F).
