Its not even helpful in baking.
It definitely is.
If a recipe calls for 3 and 3/4 cups flour, I know right away I need three 1 cup scoops of flour and one 3/4 cup scoop.
If it calls for 15/4 cups, now I need to calculate how many one cup scoops it is and also what the additional remaining fraction is in addition to how much I’ve actually measured out so far.
The more numbers you need to keep in your head when following a recipe, the more likely you are to make a mistake.
This is a great example of why volumetric recipes are inferior. With grams it’s just a single weight standard across the board. I’d much rather just use a scale, when a recipe call for 50g I know I need… a scale. When a recipe calls for 75g I know I need… a scale. No need for dirtying a bunch of inaccurate measuring implements.
