-6.667 degrees Celsius(°C)

The conversion of 20 degrees Fahrenheit to degrees Celsius involves two scales, Fahrenheit and Celsius. The Celsius scale is an SI derived unit of measuring temperature used by most countries worldwide while the Fahrenheit scale serves the same purpose but is mostly used in the United States. The freezing and boiling points define the Celsius and Fahrenheit scales. Water freezes to ice at 0 degrees Celsius indicated in the Fahrenheit scale as 32°F. It implies that they both represent a temperature reading of the same fixed point but uses a different number.

The boiling point of water at normal atmospheric pressure is 100 degrees Celsius. Therefore, the freezing and boiling points of water is 100 and 180 degrees apart in the Celsius and Fahrenheit scales respectively. When the Fahrenheit scale gives a temperature reading of 20°F, it is shown on the Celsius scale as -6.667°C.

If you want to convert the temperature in degrees Fahrenheit to degrees Celsius;

100/180 can be simplified as 5/9 or shown in decimals as 0.556

To get the temperature reading in degrees Celsius, we subtract 32 from the temperature reading in degrees Fahrenheit. The result is then multiplied by 5/9.

Fahrenheit to Celsius Converter


20 °F =-6.667 °C

20 degrees Fahrenheit(°F) = -6.667 degrees Celsius(°C)

Formula

20°F = -6.667°C is the standard principle used in the conversion. Therefore, 20 degrees Fahrenheit is equal to -6.667 degrees Celsius.

T (°C) = [T (°F) – 32] x 5/9 is the method for converting degrees Fahrenheit to degrees Celsius.

For example;

Convert 20 degrees Fahrenheit to Celsius

Solution

T (°C) = [20 °F – 32] x 5/9

= -6.667°C

Other methods that work

We first add 40 to the temperature reading in degrees Fahrenheit. You will then multiply the result by 5/9 and the subtract 40 to get the reading in degrees Celsius.

Using the above example;

20 + 40 = 60

60 x 5/9 = 33.33

33.33 – 40 = -6.67° Celsius.
