Comment on Handy temperature conversion scale.

As a metric person, I can confirm.

Indoor temperatures are basically 18-22 for most people most of the time. 15-25 covers the whole range of indoor temperatures that people with functioning heat or A/C would see.

For temperatures outside we commonly round to the nearest five: -5 and below: very cold winter weather 0 cold winter weather 5 mild winter weather 10 autumn weather 15 spring weather 20 summer weather 25 beach weather 30 heatwave 35 and higher heatwave in the Sahara

The only thing I admire of the Fahrenheit scale is that they can round to the nearest 10 and still be a little bit more precise than we are with the nearest 5. And when discussing fever temperatures, we need half degrees and Fahrenheit does not.

But it’s an absolutely awful scale for cooking.

Rounding Fahrenheit temperatures to 10 is less precise than rounding Celsius temperatures to 5.

  Yeah, but precision really doesn’t matter for the scale of “what do I wear outside”. “The 70s” and ”20-25” both convey “short sleeves, light pants or shorts”.
  
  If you want precision you shouldn’t be rounding at all, and you’re probably doing something where you should use Celsius because of convention. Rounding and precision don’t really go together.

    I agree; I was just being precise.

For cooking I think it’s mostly a matter of what you’re used to. Neither 145 or 63 are particularly “intuitive” numbers in my opinion, so as long as it’s clear which you’re using it doesn’t really matter.

  Of course, generations of humans cooked without thermometers or thermostats. You could cook with the Rankine scale if you get used to it .
  
  But let me just say, I don’t think it’s an accident France is both the originator of the Metric system and haute cuisine.
  
  Advanced cooking is as much engineering as it is art.

    So, it actually isn’t a coincidence, but not in the way that you’re implying. :)
    
    After their whole “fuck the monarchy” phase, France got deep into “throw it out and replace it with something better”. Part of that was metric, and part was “OMG they’re so many unemployed royal chefs now, what if we made it so everyone could have a chance to eat like a king for a meal?”.
    
    Surplus chefs, a cultural tilt towards trying new things, and Frances historical position giving them access to a huge array of spices, meat, dairy and fish made for a great opportunity for culinary revolution.
    
    So they’re both born from the same spirit, but one didn’t cause the other. :) Thankfully they didn’t go the way of metric time, or the French revolutionary calendar, neither of which panned out.

In Canada the scale goes higher and lower.

-5 to -10: a warm day in the winter, a break from the misery

-10 to -20: Ugh, again?

-20 to -40: Wow, it’s actually really cold out!

-40 and below: Wow, even with all my winter gear, this is going to suck.

Then sometimes in summer:

35-40: WTF, we’re hotter than the Sahara again!
