Thanks, the temperatures in the article means nothing for those who don't speak Fahrenheit...

  56.7F = 13.7C

  Because 12C ~ 21F there are some convenient temperatures to interpolate between. of course 0C = 32F and -40C = -40F but also (within a degree F): 04C = 40F 16C = 61F 28C = 82F 40C = 104F note that the last two digits are always reversed. below 0C they get less useful -08C = 18F -19C =-1.9F -31C = -23F

    Interesting strategy. I long ago memorized 20C = 68F and then adjust in increments of 5/9, which works well enough for the range of temperatures I consider habitable. I've gotten so good at this I once translated on the fly between some fellow American and European runners during a marathon. :-)

    "When it's springtime in Alaska, it's forty below". That's all I have managed to memorize about temperature conversion so far in my life.
