Why? Celsius is just as arbitrary a choice as Fahrenheit. It brings nothing extra to the table. You might as well complain that tapered pipe threads are in US inches or that astronomers use AUs and light seconds rather than meters.

In Science, global standards matter. Such as Metric and Celsius.

Fahrenheit and Celsius are defined perfectly with one another so are as easy to convert as using a different number base though. And both were originally defined at arbitrary points making neither one better suited than the other at really anything.

If they used an absolute scale like Kelvin, then sure it would be an objectively better standard, but Celsius has been defined via the Kelvin scale for over 70 years now, the same as Fahrenheit.
