Well since you're using 3/8 and you need to make 4 batches, you need to multiply 3/8 with 4 it would equal 12/8 or 1 4/8 (I could be wrong but this is my answer hopefully this helps) :) <span />
Because of wind chill, they may say that the way it feels is -3, but it was probably much warmer, but later (at 12 degrees) they were probably reporting actually temp. This is my best guess.
