it wouldn't though, it would be like 7.5 parts milk to 3 parts flour to almost a part oil to half a part sugar.
And that still being quite imprecise, using 22g or 26g sugar makes a change in taste I wouldn't want to happen uncontrolled at random. I'm also closer to 41g oil these days, wouldn't want to use 50 to make it fit some very coarse division.
Scoops of stuff also seems very imprecise. Are they at least levelled?

I also use "a pinch of salt", which doesn't have to be very precise, but if someone were to ask I could tell them "roughly 0.2g", from having just measured it. I still remembr how much I hated descriptions like "a pinch" as a cooking novice, and now I can simply measure my pinch on a scale and others can confirm their pinch on their scale until it about matches 0.2g too. How would that work in imperial?
