Way back in the day some people called it centigrade. Got me all confused thinking it was a seperate unit. I think it was just a way to emphasize how metricky their system of temperatures is.

Onto time Everything else in life is based on 10s oe 100s but time is divided into 60ths to fit on a circle. Space and Time were later proven to be linked but they were alwsys known to be since time was first set to the sun. Time fits on a cirlle because both the sun and earth are spheroids. Everything involving circles involves degrees. Units more precise than degrees are called minutes and seconds.

So then one hour=1° but one hour on a clock is a 30° angle

Then for some reason we picked the degeee and the° symbol to also measure temperature. I haven't found the answer to that.
