Formula and Calculation
The formula to convert Fahrenheit to Celsius is:
Celsius = (Fahrenheit - 32) * 5/9
To convert 55°F to Celsius, simply substitute the Fahrenheit value into the formula:
Celsius = (55 - 32) * 5/9
Step-by-Step Conversion
-
Subtract 32 from Fahrenheit:
55 – 32 = 23 -
Multiply the result by 5/9:
23 * 5/9 = 12.78 -
Round the answer to the nearest tenth:
Celsius = 12.8°C
