^lol. i have a thermometer in my room that measures both C & F and when you look at it the difference between ~11 C = ~20 F.
what you're getting from google is 7 C = 44.6 F and that's cuz C & F don't both start at zero. C starts at 0 while F starts at 32. So you can blame the American's for yet another useless measurement system like feet, yards, miles, etc. I wish the whole world just used the metric system.
edit:
44.6 - 32 = 12.6 F and 7 C - 0 C = 7 C therefore 7 C = 12.6 F
and i haven't taken a Calculus, Chemistry or Physics class in years.
