I'm an American biochemist, I also never learned the english system because my school transitioned to metric too fast. The mental burden of trying to cook using english units after working all day in the lab using that same part of my brain leads me to just not want to cook 95% of the time. But when I do cook I have optimized processes for my few simple recipes. When I bake I usually use a metric recipe or convert a English one, and optimize it before making a large batch of something.
