Temperature is weird in farenheit too.
Why is 32 degrees where water freezes? Or 212 when it boils?
Celsius is more intuitive, as water freezes at 0, and boils at 100 (at sea level). Since water is such an important part of our daily lives, this makes sense. Celsius also uses the same size units as Kelvin, which is what scientists use (0 kelvin is absolute zero, -459 f, -273 C). Celsius just offsets this so the temperatures we use in our daily lives are in a more meaningful scale. Like a cold winter day is -5 C, rather than 268 K, and a pleasant day outside is 20 degrees C, rather than 293 K).
Farenheit units are smaller, which is nice, but we just use decimals in Celsius if we need that precision (usually just .5 for baking/cooking or setting your thermostat)
