minus-squarecheese_greater@lemmy.worldOPlinkfedilinkarrow-up2·1 year agoIs there a quick+dirty F -> C conversion? I know its something something * 0 + 32 or some shit but I’d love a super loose rule or affirmation of that if you know
minus-squareTauZerolinkfedilinkarrow-up3·1 year agoThe full formula is (F-32)*(5/9). I have difficulty multiplying by 5/9 in my head, so the quick-and-dirty option is to subtract 32 and simply divide by 2. 50F - 32 = 18, divide by 2 = 9C (compare to actual value: 10C)
