A groundbreaking new way to think about Fahrenheit and Celsius
I have come up with a new way to think about Fahrenheit and Celsius. Behold, my masterpiece:
Very Water Very Cold Freezes Nice Hot -20C 0C 20C 40C 0F 32F 70F 100F | | | | -------------------------------------------------- | | | 40F 50F 82F 4C 10C 28C
Read on to learn about how this amazing cultural and scientific product came to be...
Here's a funny and informative graphic that was going around a while ago:
So from here we can see that Fahrenheit is clearly the superior scale for human environments.
But how does someone familiar with Celsius understand what it's like outside based on the Fahrenheit weather, and vice-versa?
This Hank Green tweet proposed a simple way to think about Celsius:
Hey, having a hard time with Celsius? Ignore the second number and it’s basically just how hot it is on a scale of 0 to 5.
Pretty good, but I thought, it could be better. I'd like to have a mental scale that I think of as analogous to 0–100 in F. Let's start with a few facts:
- around 70 F is "nice"
- 70 F is 21 C
- 32 F - water freezes
- 0 C - water freezes
- 0 F is -18 C
- 100 F 38 C
So if we're going for a good enough mental scale, maybe we can say that the range of Celsius aligning with Fahrenheit is about -20–40. There is also the sort-of pattern that frozen water is about a third from the bottom of the range, nice weather is about 2/3 from the bottom.
So we have:
- 0 is Very Cold
- 32 is Frozen Water
- 70 is Nice
- 100 is Very Hot
- -20 is Very Cold
- 0 is Frozen Water
- 20 is Nice
- 40 is Very Hot
In addition to that, a few other mnemonics/markers:
- 40F is 4.4C
- 50F is 10C (as in 50.0̅ is 10.0̅ which is very shocking to me)
- 82F is 28C
