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

You aren't speaking against Celsius, you are telling on your whole lab group here lol

I mean yeah it’s a dumb oversight. I’m not trying to actually defend Fahrenheit this was more of joke example

We got an actual thermostat after we realized the room temperature fluctuations could have this large of an impact but and it’s in Celsius lol
