Fahrenheit to Celsius |

| |
Type a value in either field to convert from Fahrenheit to Celsius or from Celsius to Fahrenheit:
212 °F = 100 °C - boiling point of water
32 °F = 0 °C - freezing point of water
The conversion formulas between °F and °C are:
[°C] = ([°F] - 32) × 5/9
[°F] = [°C] × 9/5 + 32
Fahrenheit is a temperature scale used for describing temperatures in Fahrenheit degrees (°F)
It is most commonly used in the United States in weather forecasts and to describe temperatures inside houses, offices, etc.
Celsius is also a temperature scale that describes temperatures in Celius degrees (°C) and it is used in everywhere else outside the US.
The Fahrenheit and Celsius scales coincide at -40°.
Because of the complex convesion formula people often use fahrenheit to celsius calculators to convert temperatures. Remembering a few °C and °F pairs can be useful in everyday life, such as:
- 0°C is the freezing point of water (or more accurately the melting point of ice) and it is 32°F
- A 1 Celsius change is a change of 1.8 Fahrenheits while a 1 Fahrenheit change translates to a change of 0.55 Celsius. This is one of the easiest way to convert them if you know that 0°C = 32°F
- 100°F is really really hot in the summer and it is 38°C so when people talk about a 100°F heatwave, it means hot.
- 37 degrees Celsius is the equivalent of 98.6 degrees Fahrenheit, or normal body temperature. A fever in Celsius is a temperature greater than 38 degrees, or the equivalent of 100.4 degrees Fahrenheit. Also, a temperature of 39 degrees Celsius/102 degrees Fahrenheit is not dangerous in and of itself, although it should prompt the individual to seek medical attention if it persists.
- Air conditioners should be set to 77-78°F or 25-26°C. Most people set theirs lower because they like to wear a sweater inside the house in the summer and a tank top in the winter.
- Your thermostat in the winter is ideally set to about 69°F or 20°C. This saves on your heating bill and also helps saving the environment.
