What is the Celsius equivalent of an F-C of 85 degrees?

To convert Fahrenheit to Celsius, you can use the formula:

[ C = \frac{(F - 32) \times 5}{9} ]

In this case, to find the Celsius equivalent of 85 degrees Fahrenheit, follow these steps:

1. Subtract 32 from 85:

[ 85 - 32 = 53 ]

2. Multiply the result by 5:

[ 53 \times 5 = 265 ]

3. Divide by 9 to get the Celsius temperature:

[ \frac{265}{9} \approx 29.44 ]

When rounded to one decimal place, this value is approximately 29.4 degrees Celsius, aligning perfectly with the correct answer. This conversion is based on the relationship defined by the temperature scales, where the freezing and boiling points of water are set at 0°C and 100°C in Celsius, and 32°F and 212°F in Fahrenheit, respectively. This understanding is crucial for translating temperature readings between different units accurately.
