How can you be sure that "all of your regular coffee cups are exactly 250ml"? And what about teaspoon? And everything else?
Everyone here is obviously biased toward his/her own measurement system based on our experience, but the fact that "3 cups and a half of milk" is more precise than "875mL of milk" is clearly false.
I didn't say anything about Imperial being more precise.
I'm saying it's often more useful.
1 cup mix, 1 cup milk + 1 egg.
1 pint of beer.
1 teaspoon of sugar.
These are things everyone can understand.
You can put the ml on the side of the label.
"That guy is 6 feet tall, about 180 lbs."
Is better than metric for most people.
"I'll have a glass of wine" instead of "I'll have 240 ml of wine"
Any one of you who orders beer by the 'ml' can keep arguing with me, but I suspect you all order 'pints' in which case you should consider for a moment why you do that.
