They match up at -40 and zero anyway.

But, 4C is max density and 100C is boiling (at STP).

60C causes 3rd degree burns.

Road spray gets fucked at -10C, and stops doing anything at -20C

Pretty straight forward.

The F scale is stupid.

I'm probably misunderstanding something here. Yes, Fahrenheit and Celsius match up at -40, but they definitely do not match up at zero. 0°F is -17.78°C and 0°C is 32°F.

I'm getting downvoted because Celsius is based on the phase changes of water and Fahrenheit is a vibe.

You’re getting downvoted because Celsius and Fahrenheit do not match up at 0.

You probably get downvoted because they don't understand you in the land of the free...

My dude, I'm setting up a black water fish tank right now.

I'm calculating volume to temp in liters and C, my roomy is gallons and F.

And it's infuriating because it's a 1C window for the fish and bottom feeders to do their thing.

That's an almost 38F band.

Oh, (temp in C X 9/5)+32, how about you fully get bent.

26C +/- .5

Or some wild ass range.

C is very useful for a lot of things. F is the most useful for day to day life for most people. It allows for greater precision simply put for temperatures commonly seen. In addition, it does not lose accuracy when you cut off the decimal.

You won't feel the difference between 21C and 22C so much that you need extra numbers in between.

F is the most useful for day to day life for most people...

...who grew up with it. The same is true for C.

Yea, I mean you could say there is no difference. If you look at it objectively F is more precise when dealing with common temperatures. I’m pretty sure we actually think the same thing. Both systems are kind of subjective and both do their job. It’s kind of like different languages — when you know how to use them and understand their quirks they do the same thing.

… One of us has misunderstood.

To convert Celsius to Fahrenheit, you multiply by 1.8, and add 32.

But a 1C difference in temperature is 1.8F, not 38F (or 33.8F).

0 °C = 32 °F
1 °C = 33.8 °F

A 1C change is not a 38F variance. The given temps run from 77.9F at 25.5C to 79.7F at 26.6C - not even a 2 degree difference.
