Celsius and Fahrenheit are two scales used in the conversion of 100 degrees Fahrenheit to degrees Celsius.

## 37.778 degrees Celsius(°C)

Celsius and Fahrenheit are two scales used in the conversion of 100 degrees Fahrenheit to degrees Celsius. The Celsius scale is used by most countries worldwide as an SI derived unit of measuring temperature. The Fahrenheit scale was adopted by the United States and also serves the same purpose. The two scales are defined by the freezing and boiling points of water. Water freezes to ice at 0 degrees Celsius which is shown in the Fahrenheit scale as 32°F. This means that they both start at different numbers but represent the same temperature reading. The boiling point of water at normal atmospheric pressure is 100 degrees Celsius. In the Fahrenheit scale, it reads at 212°F which shows that the two scales rise at different rates.Therefore, the freezing and boiling points of water is 100 and 180 degrees apart in the Celsius and Fahrenheit scales respectively. To determine the conversion from degrees Fahrenheit to degrees Celsius; 100/180 can be simplified as 5/9 or shown in decimals as 0.566 First, we will subtract 32 from the temperature in degrees Fahrenheit. Multiply the result by 5/9 to find the temperature in degrees Celsius.

### Fahrenheit to Celsius Converter

#### `100 degrees Fahrenheit(°F) = 37.778 degrees Celsius(°C)`

##### Formula
100°F = 37.778°C is the standard principle used in the conversion. Therefore, 100 degrees Fahrenheit is equivalent to 37.778°C. T (°C) = [T (°F) – 32] x 5/9 is the method for converting degrees Fahrenheit to degrees Celsius.
##### For example;
Convert 100 degrees Fahrenheit to degrees Celsius.
##### Solution
T (°C) = [100 °F – 32] x 5/9 = 37.778° Celsius

#### Other methods that work

We first add 40 to the temperature in degrees Fahrenheit. Multiply the result by 5/9 and then subtract from 40 to get the temperature reading in degrees Celsius. Using the above example; 100 + 40 = 140 140 x 5/9 = 77.78 77.78 – 40 = 37.78° Celsius.
