**Why we would 32 in Celsius to Fahrenheit & Vice Versa.**

Hey fellows, please tell me why we add 32 to celsius to Fahrenheit conversion and vice versa. According to my mind, I derive C to F formula of my own. I do the following.

1)I look and choose the same scale of F and C. The most obvious of which is freezing and boiling point. For F (32-212) and for C (0-100).

2)Now to derive the formula for C to F, i divided 180/100 =1.8 it means that if celsius then the corresponding F is 1.8. So I now want to know how much is 37C in Fahrenheit then I multiplied it by 1.8*37=66.6 which is not true unless I add 32 to this. But why would I actually do that? Please explain 32 celsius to Fahrenheit.
