On the other hand it dilutes the effect of lower values because a lot of them are double digit. 20F, 40F, 60F… all double digit, but wildly varying. On the other hand, with Celsius you get:

• Below 0: There’s ice/snow.
• 0: Things are freezing/thawing (depending on what the temperature was before.
• 10s (Spring): T-shirt weather.
• 10s (Fall): Sweater weather.
• 20s: Nice in the sun.
• 30s: Nice in the shade.
• 40s: THIS IS PUNISHMENT FOR OUR HUBRIS.
