To convert 85 degrees Fahrenheit to Celsius, we use the formula: °C = (°F - 32) × 5/9. This conversion formula is based on the fact that the freezing point of water is 32 degrees Fahrenheit and 0 degrees Celsius, and the boiling point of water is 212 degrees Fahrenheit and 100 degrees Celsius.
Understanding the Conversion Process
The process involves subtracting 32 from the Fahrenheit temperature to adjust for the difference in the zero points of the two scales, and then multiplying by 5⁄9 to account for the difference in the size of the degree units between the two scales. Applying this formula to 85 degrees Fahrenheit gives us: °C = (85 - 32) × 5⁄9.
Performing the Calculation
Subtracting 32 from 85 yields 53. Then, multiplying 53 by 5 gives 265, and dividing 265 by 9 results in approximately 29.44. Therefore, 85 degrees Fahrenheit is equivalent to approximately 29.44 degrees Celsius.
