It's not that simple, because melting ice or evaporating liquid water in itself requires a set amount of energy, without the temperature changing.
>water cannot cool below 0°C until the entire thermodynamic unit is frozen solid
Naturally other systems also don't take this into account, but it's a specific weakness of Celsius.
>300% of heat goes into melting ice 0-4°C
>100% heat goes into heating the water from 4° to 99°
>literally cannot heat above 100° and it again takes like 300% of energy to evaporate
Doesn't make any fucking sense, strictly speaking.

The main advantage of decimal/metric really is just that it's impossible to misunderstabnd or misinterprete
>unit is 100 other units
>that unit also is 100 other units
>or maybe 1000, depends
>sometimes 10
