For above freezing, terrestrial temperatures, Canadians have long depended on the “double it and add 30” rule to understand freedom temperature units while travelling.
F vs c is easier if you think in bands of temps. 15 C is about 60 F. Each ten degrees difference in F is about 5 degrees different in C. So 20 C is about 70 F. 10 C is about 50 F.
I’ve worked in some capacity of manufacturing for a while now so I’ve gotten used to going back and forth. You’ll get it!
Practice by thinking what the other would be any time someone mentions one.
1kg = double it and add a little lb
1lb = just under half kg
1cm = just under half in
1in = a little more than double cm
F vs C = give up
1 kg = 2 * lb + 1/5 * lb (lucky for us 5 is a prime factor of base 10)
To easily convert between F and C, simply cool the thing down to -40° and you’re good you go

C to F = 100 is too hot, 0 is too cold, 50 is just righ- ah damn it

For F and C, there’s a 10% variation from double/divide (5/9 vs 9/5).
So add or subtract 10% after doing that part.
It’s exactly (C*9/5)+32. That’s not a rough formula, it’s exact.
Ok mr advanced mathematics with complex numbers
basically me as I’m slowly learning metric
