# English-French dictionary » Temperature Conversion: Fahrenheit to Celsius Converter

The Fahrenheit temperature scale was the first widely used standardized temperature scale. It was named after Daniel Gabriel Fahrenheit, a physicist who worked as an inventor, making thermometers and other scientific measuring instruments.

The symbol for Fahrenheit is °F.

The Dutch physicist wanted to create a scale with no negative values. The original Fahrenheit scale had three fixed points:

• The freezing point of a solution made from equal parts of water and salt, which was set at 0 °F.
• The temperature at which ice begins to form on the surface of water, which was set at 32 °F.
• The temperature of the human body, which was set at 96 °F.

Later, the Fahrenheit scale was redefined: the freezing point of water was set at 32 °F, and the boiling point of water was set at 212 °F. The scale was divided into 180 degrees, which corresponded to the values of atmospheric pressure measured at sea level.

The Fahrenheit temperature scale was used worldwide until the 1960s. In England, Celsius was adopted around this time, making Fahrenheit to Celsius conversion interesting. By the end of the 20th century, Fahrenheit remained the official temperature scale only in the United States and a few associated states, such as the Bahamas, Belize, and the Cayman Islands. However, not only weather reports but also recipes are typically given in Fahrenheit in these regions.

## Celsius to Fahrenheit Conversion

Converting Celsius to Fahrenheit cannot be done one-to-one. The reason is that while the Fahrenheit scale is divided into 180 units, the Celsius temperature scale is divided into 100 units.

Therefore, you need to use the Celsius to Fahrenheit conversion formula: [°C] = ([°F] − 32) ×   5 ⁄ 9

## Fahrenheit to Celsius Conversion

The Fahrenheit to Celsius conversion formula is: [°F] = [°C] ×   9 ⁄ 5 + 32

## Typical Temperature Values in Fahrenheit

• Freezing point of water: 0 °C=32 °F
• Average room temperature: 21 °C=70 °F
• Human body temperature: 37 °C=98.6 °F
• Feverish condition: 38 °C=100 °F
• Boiling point of water: 100 °C=212 °F
