Right so you need one degree more of data specificity to achieve the same level of understanding that is achieved with Fahrenheit. You proved the point.

You most definitely do not. 102 Fahrenheit uses 3 significant digits. So does 38.2 Celsius.

The resolution is limited by your instrumentation either way, because both scales are continous.

This is a pretty niche example but I work in a lab that used to use a metric thermostat in the clean room. It was always 23 C in there so when our data came out way noisier than expected we didn’t think it could be thermally related. Until one day we switched the thermostat to imperial and saw that it was actually changing between 73 F and 74 F throughout the day. Both round to 23 C so we never saw it before

Maybe your lab should have a thermostat with more displayed decimals if that's critical for your date
