30 is hot.

20 is nice.

10 is cold.

0 is ice.

Not hard to remember for converting Celsius to how humans typically perceive temperature.

[timschmidt]

My problem isn't remembering the scale, it's that Fahrenheit offers me double the effective resolution and descriptive accuracy without awkward decimal points in the numbers used.

I like my room at 73F, not 72F or 74F, and I can feel the difference. That's 22.77C. :-/

My main observation in temperature scale and imperial lengths discussions om the Internet is that Americans seem to have a strange aversion against fractional parts of numbers, as if those were irrational.

(On the other hand a lot of Americans consume fava beans.)

[timschmidt]

Au contraire base 12 measurement is _all about the fractions_. 12 can be divided evenly by 2, 3, 4, and 6. Metric gets 5 and 2. By that measure it's y'all that are afraid of the small numbers.

US units are pinned to Metric standards anyway. We're just using the most creative ratios. :)

American, I think we use fractions all the time: 7/8 inch hardware tools, 3/4 measuring cup in cooking, etc. Especially awkward when you have human distances, because you have to mix feet + inches: 3 feet 4 and 1/4 inches.

It was a dream once I got a metric tape measurer and realized that using centimeters eliminates the need to do annoying conversions.

I found this take from 'Torque Test Channel' (tests battery tools) humorous: https://www.youtube.com/watch?v=2QUum9NymZY

[timschmidt]

Brilliant and hilarious.

Most temperature sensors are accurate to 0.1C. Most weather forecast is 0.5C resolution. So yeah only explanation to Americans behavior is an aversion against fractional numbers as you said.

> I like my room at 73F, not 72F or 74F, and I can feel the difference.

I suspect you wouldn't notice if it changed by a degree.

[timschmidt]

You'd be wrong. Happens.

[lunarlull]

I might be, but I don't think so. It certainly happens less often than something like people making ridiculous easily disprovable claims.

[timeon]

I like my room exactly at 21C. Any F number is Greek to me.

Remembering is more about what you are used to here.

[lotsofpulp]

Perceiving temperature involves dew point and relative humidity, not just temperature.

[k_roy]

Okay. Or, hear me out.

On a scale from 0-100, you have very cold and very hot.

Or you’ve got from 0-45. Where 0 is “meh” cold and 45 is incredibly warm.

So you’ve got a nice little 0-100 scale that all humans are going to experience just living that goes from very cold to very hot.

Or you’ve got a useless 0-100 scale that the bottom just means freezing, and ignores every pain point of being really cold below that, and anything really greater than 50C only has practical applications in cooking.

[adammarples]

0 isn't the bottom of the celcius temperature scale, there are negative numbers

[artursapek]

Cool yeah let's compress the entire scale to 0-35 and waste the other 65 up to 100 lol yeah what a great scale

[werdnapk]

The "entire scale" has no maximum. So your waste of the Celsius scale from 35-100 is Fahrenheits waste of the scale from 0-32 or whatever you're trying to base your comments on.
