@Elliptica @VD15 @egirlyuumimain >1 ts, 1 tbs, 1 cup are nicer to work with than 4.9ml, 14.8ml, 236.6ml.
Then don't do that?

You clearly can easily work with 5mL, 10mL, 15mL, 20mL, 100mL, 200mL and 240mL, adjusting as needed - as you can easily wack on or off 5mL or 10mL or 100mL or 50mL or 1mL as needed, or half the value, meanwhile you cannot do the same when working with tablespoons or cups and end up degenerating into stuff like ⅛ cup.

>it's easier to divide and multiply stuff when your starting unit is increments of 1
It's easier to divide and multiple stuff when you can trivially arrive at exact values instead of endlessly undershooting and overshooting.

>Basically establishing a scale that works within the context of their field.
mL works perfectly fine for the field whether you round to 25mL or 1mL.

Cups and tablespoons are more complicated and much easier to get wrong than mL (add 100mL of milk vs add 1 cup and 6 tablespoons of milk).

>incremental metric measuring cups would be silly.
Such cups have never been made.
