That’s the whole point, the recipes aren’t in oz and pounds, they’re in cups and table/teaspoons

F has nothing to do with how a human feels. 0 f was literally just a very cold day that happened once. You’re just used to it, the same way people who use c are used to it and feel it very intuitively. A scale that actually was human would probably be logarithmic since we dont feel temperature linearly, and the 0 would be at 20c ~68 f since that is the temperature that’s most comfortable for people, with positive numbers being hot temperatures and negative numbers being cold

The biggest issue with imperial recipes is the constant use of measures by volume. If everything was in weight ounces it would be alright, but a lot of recipes insist on measuring solids by volume, like a cup of flour, a teaspoon of sugar etc, making them a lot harder to replicate consistently. My flour could be denser, my sugar could be finer, if things were measure by the actual mass such things would not matter but instead I have to fill a cup and pray to the gods that my cup of Ecuadorian flour has the same density as the one on the recipe (it almost never is)
