Fahrenheit (abbreviations: F, or °F, or deg F): is a temperature scale based on one proposed in 1724 by Amsterdam-based physicist Daniel Gabriel Fahrenheit (1686–1736), with regard to whom the scale is named.
Celsius (abbreviations: C, or °C, or deg C): also known as centigrade, is a SI metric scale and unit of measurement for temperature and used by most countries in the world. It is named with regard to the Swedish astronomer Anders Celsius (1701–1744), who developed a similar temperature scale.
How to Convert Degree Fahrenheit to Degree Celsius
Example: How many degree Celsius are equivalent to 55.11 degree Fahrenheit?
As;
1 degree Fahrenheit = (5/9)*(X-32) degree Celsius
55.11 degree Fahrenheit = Y degree Celsius
Assuming Y is the answer, and by substitution principle;
Y equals ( (5/9)*(55.11-32) ) over 1, where X is substituted by 55.11
(i.e.) Y = ( (5/9)*(55.11-32) ) / 1 = 12.838888888889 degree Celsius
Answer is: 12.838888888889 degree Celsius are equivalent to 55.11 degree Fahrenheit.
