First time I hear about it, noticed the accuracy drops off significantly if the last number is >1? 51F ~ 15C 52F ~ 25C 59F ~ 95C? Subtract 30, divide by 2 works well enough heh

>Subtract 30, divide by 2 works well enough heh That's close enough for most purposes, but (F)5/9-32=(C) provides better precision.
