## Fahrenheit

Definition: Fahrenheit (°F) is a unit of temperature that was widely used before metrication. Two points describe it: water freezes at 32°F, and water boiling point is 212°F at sea level and normal atmospheric pressure. The freezing and boiling point interval is divided into 180 parts.

## Celsius

Definition: The Celsius (°C) is an SI (International System of Units) derived temperature unit. Also called centigrade, the scale is based on 0°  for the freezing point and 100° for the boiling point of water at standard atmosphere and sea level pressure. It has a 100-degree interval between the defined point.

Fahrenheit to Celsius Conversion Chart How to convert Fahrenheit to Celsius. 0 degrees Fahrenheit is equal to –17.77778 degrees Celsius: 0 °F = -17.77778 °C. The temperature is T in degrees Celsius.

## Temperature Converter Formula

C = Celsius ; F = Fahrenheit ; R = Reaumur ; K = Kelvin

0 °F = -17.77778 °C

To convert temperatures in degrees Celsius to Fahrenheit, multiply by 1.8 (or 9/5) and add 32.

Example: (30°C x 1.8) + 32 = 86°F

## How to Convert Fahrenheit to Celsius

The simple rule to convert Fahrenheit to Celsius is just minus 32 from the Fahrenheit value and divide by 1.8 that value.

T(°C) = (T(°F) – 32) × 5/9

or

T(°C) = (T(°F) – 32) / (9/5)

or

T(°C) = (T(°F) – 32) / 1.8

Example
Convert 70 degrees Fahrenheit to degrees Celsius:

T(°C) = (70°F – 32) × 5/9 = 21.11 °C

For example,

100 Fahrenheit to Celsius.
100-32 = 68/1.8 = 37.77

## How Do You Convert Celsius to Fahrenheit?

multiply by 1.8 (or 9/5) and add 32.

Example: (30°C x 1.8) + 32 = 86°F’
