Although this looks like a math fail, this one is easy to explain, as Celsius is a relative scale, Google converts to an absolute scale to do
the math (Kelvin) – it wouldn’t make sense otherwise.
0C = 273.15K, 0C + 0C = 273.15K + 273.15K = 546.3K = 273.15C

I would actually make more sense to compute
0 degrees Celsius + 0 Celsius degrees
degrees Celsius = an actual temperature
Celsius degrees = the amount of temperature change between the ticks on the Celsius scale
