They said cups. A cup of ANY liquid is 8 oz. So 16-24 fluid ounces. Or 2-3 cups.
These people is really stupid and dumb. Everybody I know uses coffee MUGS, not cups. A cup of tea but not a mug of tea. Are these people living under a rock? How many cups in a mug?
A coffee cup is 6 ounces A coffee mug is 2 coffee cups = “12 ounces. Source quora.com
“A cup of ANY liquid is 8 oz.”
IIRC, when it comes to “a cup of coffee”, it’s typically 6 oz.
With my Keurig (thank you, Rush, for that tip years ago!), my cups of coffee are 10 oz. About 3 a day.
