" Admittedly, I'm not entirely sure why being a non-linear transform gets the OP so riled up." Because it's harder to calculate mentally One can approximate 2lb to 1kg roughly, 1mi ~ 1.6km, but for Fahrenheit this is harder One solution is to establish a set point ( 70F = 21.1C, approximate to 20C ) then work in differences, since 1.8deltaF = 1deltaC so, 2dF ~ 1dC (or 10dF ~ 5dC) Hence, 90F is approximately 30C (exact value, 32.2C) |
