You certainly didn't win any arguments with those claims.

0-100f is not anywhere close to the scale people see in the weather anywhere most people live. Taking where I've ever lived as an example:

  • Melbourne ~ 30-120 f vs 0-45c,
  • Gladstone QLD ~40-120f vs 5-45c,
  • Pilbara ~65-130f vs 15c-50c,
  • Dubai ~55-120f vs 20c-45c,
  • Houston TX ~ 30-120f vs 0-45c,
  • Pittsburg PA ~10-90 vs -15-30c.

The most iimportant number with respect to the weather is freezing, it's handy knowing if you're dealing with ice. The standard range for where people live is not -40 degrees, something like 2/3 of the world live between the tropics and will never see freezing or below. The -40 number makes sense if you live in Alaska or Siberia and maybe even somewhere like Minnesota, but certainly not to someone in India or Indonesia....

Neither scale is relative to cooking (which isequally arbitrary for both), though metric is easier for things like brewing 80°C tea since you need 4/5th a cup boiling water and 1/5 a cup and no thermometer.

The "feel" of the weather is hugely impacted by humidity which is why every forecast has a "feels like" measure and why 90°f in Dubai is lovely but 90°f in Houston is miserable. The increments of 10f doesn't make sense at all, though seems to be a common perception among people who prefer fahrenheit

The comment about farenheit being more granular would be true in an alternative universe where decimals don't exist, but not in this one.

Americans literally like farenheit more because it's familiar, any other rationalisation is nonsense. Both measures make perfect sense after you've taken the time to learn them and use them daily (I know this firsthand).

What doesn't make sense about it? You can tell another person it's in the 30s outside, and you have efficiently communicated more information than is possible when using Celsius. You'd have to say it's between 4 and negative 1, which is just lame. And this remains true across every temperature, because of a variety of factors which I explained above.

In every climate which you mentioned above, it's easier to communicate how hot or cold it is outside using Fahrenheit. This is because all of the numbers being used are non-negative integers (aka natural numbers). Even the triple digit ones are one-ten or one-twenty.

I wonder why mathematicians named them that? Possibly because they come naturally? Unlike negative one point seven.

It doesn't tell you anything that Celsius can't with a 5 degree swing. This the absolute peak of arbitrary, both 5s and 10s are easy scales to work with. Your example of between 4 and negative one is deranged. I'm in houston right, it's 90°f - if I want to comunnicate that to my yankee girlfriend I'd say "babe it's 90° outside, might get up to one hundred" and so far, you're right this is easy to articulate. If I want to communicate that same information to my mum, I'd say "hey it's 30° outside, might get up to 35°". Both cases convey information with the same accuracy, both cases I haven't mentioned humidity, which for actual temperature feel has a way higher influence then 5 degrees, the extra information I'd gain by strictly converting 31-37.8°C is junk data, the farenheit measure is approximated to begin with and because of a humidity swing carries a huge variability in actual "feel" anyway. I tried to explain this above and clearly failed, as your response doesn't touch on this at all and just insists that people who think in metric don't default to easy to work with numbers.

In every climate which you mentioned above, it's easier to communicate how hot or cold it is outside using Fahrenheit. This is because all of the numbers being used are non-negative integers (aka natural numbers). Even the triple digit ones are one-ten or one-twenty.

The only place with negative integers was Pittsburg, so that point doesn't make sense for the rest and even if it was, your argument is insane. Saying negative 5 is no harder than saying 25, plus having negatives where snow and ice come into play makes it obvious when to be careful outside. I mean your argument here just makes no sense, if there is some added complexity to saying "negative" then it is surely comparable to having to remember a random number of 32. Literal kindergardeners understand negative numbers. Neither this or remembering the 32 number add any meaningful complexity and certainly have 0 impact on anyone's actual use of either scale.

Literal kindergardeners understand negative numbers.

Literal adults have trouble with negative numbers. I can't do this all over again, sorry and have a nice day. Hopefully it's somewhere in the 80s wherever you are

Mate I have to reply to that, because it's such an insane claim - the US, the only country that doesn't use °C, has this huge reliance on a monstrously complex credit system (obviously the entire concept of credit is reliant on the concept of debt and negatives). It's flat out insane to suggest that the same people who live and function with such a credit system conceptually struggle with the fundamentals negative numbers. It's a mind boggling claim.

Anyway, have a good one.

[–] [email protected] 1 points 3 weeks ago

Yes, as we both know, there aren't any Americans who struggle with a low credit score and end up with insurmountable debt...??? Credit is reliant on debt and negatives, and people get screwed by their lack of understanding it every single day. Same with the lottery, except with big numbers and percentages. America is profoundly dysfunctional and it's frequently the people who are bad at math that get exploited.
