Hint : We know that 100 degrees Fahrenheit is equivalent to 37.78 degrees Celsius. We have to subtract 32 from the value in Fahrenheit, then, multiply this with 5 and divide it with 9 for converting the given degrees Fahrenheit value to degrees Celsius precisely.

Complete step-by-step solution:
A temperature in Fahrenheit can be converted to Celsius using the formula, C=(F32)×59 .
So, the Celsius value for 80 F is =[(8032)×59] C
=[48×59] C
 =26.667 C
Therefore, the correct answer is 80 F is equal to 26.667 C.

Additional Information:
In 1724 , the German physicist Daniel Gabriel Fahrenheit first proposed a temperature scale which is based on 32 as the freezing point of water and 212 as the boiling point of water, and the interval is divided into 180 equal parts, each division representing 1 F. This temperature scale is known as Fahrenheit scale.
Daniel Gabriel Fahrenheit initially chose values of 30 and 90 for the freezing point and normal body temperature of water, respectively, where zero on his scale was the temperature of the same ice-salt mixture. These values were later corrected to 32 and 96 , but on the final scale, the latter had to be adjusted to 98.6 . 459.67 is the absolute zero value in Fahrenheit scale.
In 1742 , the Swedish astronomer Anders Celsius introduced a temperature scale which based on 0 C as the boiling point of water and 100 C as the freezing point of water (but it was reinverted in today’s form later), and the interval is divided into 100 equal parts, each division representing 1 C. this temperature scale is known as Celsius scale.
Now, this scale does not depend upon the boiling and freezing point of water. It has been adopted and is based on the triple point of Vienna Standard Mean ocean water. The absolute zero value of this scale is 273.15 C.

Note:
In the United States, Fahrenheit scale is highly used, whereas, the Celsius or Centigrade scale is used in most other countries and for scientific purposes around the world. Average human body temperature is 37 C in Celsius scale and 98.6 F in Fahrenheit scale.
