How to convert Celsius to Fahrenheit
Multiply the Celsius temperature by 9/5 (1.8) and then add 32. For example, 25 °C × 1.8 + 32 = 77 °F. A rough mental shortcut is to double the Celsius value and add 30: 25 °C is about 80 °F. The two scales meet at −40, where −40 °C equals −40 °F. The converter above shows the exact value plus Kelvin.
