Question 38

80 Fahrenheit converts to 26.7 Celsius.

To convert 80 degrees Fahrenheit to Celsius, the formula used is (F - 32) × 5/9 = C. Applying this formula, we find that 80 Fahrenheit is equivalent to 26.7 Celsius.

A) 26.7C

This option is correct because using the conversion formula: (80 - 32) × 5/9 = 26.7. This calculation confirms that 80 Fahrenheit accurately converts to 26.7 Celsius.

B) 86.4C

This option is incorrect as it suggests a far higher temperature. If we were to apply the conversion formula, we would find that this value does not correspond to any reasonable conversion from Fahrenheit to Celsius, thereby making it inaccurate.

C) 62.2C

This option is incorrect as well. This value does not match the calculated Celsius equivalent of 80 Fahrenheit. The conversion formula shows that 62.2C is not a valid conversion from 80 Fahrenheit.

D) 76.4C

This option is also incorrect. Similar to the previous options, 76.4C significantly deviates from the correct conversion. The formula indicates that this temperature is not achievable from 80 Fahrenheit.

Conclusion

The correct conversion of 80 Fahrenheit to Celsius is definitively 26.7C, as verified through the appropriate formula. All other options incorrectly represent the conversion and do not align with the temperature conversion principles. Thus, Option A stands out as the only correct answer.
