To convert Fahrenheit to Celsius, the formula you use is:
                        C=(F−32)×5÷9​
Where:
- CC is the temperature in Celsius,
- FF is the temperature in Fahrenheit.
Now, let’s break it down step by step:
- Start with the temperature in Fahrenheit:
F=13
- Subtract 32 from the Fahrenheit temperature:
13−32=−19
- Multiply by 5:
−19×5=−95
- Divide by 9:
−95​÷9≈−10.56
So, 13°F is approximately -10.56°C.
why this works:
- The Fahrenheit scale is based on freezing at 32°F and boiling at 212°F, whereas the Celsius scale is based on freezing at 0°C and boiling at 100°C.
- The conversion formula adjusts for this difference by subtracting 32 (the freezing point of water in Fahrenheit) and then scaling by the ratio of the Celsius to Fahrenheit degree sizes, which is 5/9.
