Ho many ounces in a cup of coffee?

[ho'ard]

I've been filling my 4 cup Mr. Coffee with a 2-cup Pyrex measuring cup . . . a full 2 cups or water fills the cannister about to the 3 1/2 cup mark.
Is there some sort of standard I'm not aware of that says a cup of coffee is really 4.something ounces?

[Filliam H. Muffman]

There is some standard that a "cup" of coffee is 5 ounces so a carafe for a coffee maker rated for 10 cups holds about 50 ounces. I found some sites that say the manuals for Cuisinart and Krups makers have this listed but I was not interested enough to track them down.

Doesn't the Mr. Coffee have a carafe to transport water with ?

[Mac1337]

It is a well known secret that a cup is not really cup. I can fill up the whole Mr. Coffee pot with 4 coffee mugs of water. I think it is rated at 10 or 12 cups. One amusing thing that I have never been able to explain is that I sometimes get less water out than I put in.

Doesn't the dry coffee grounds absorb and retain a percentage of the water ?

If you weigh the grounds before perking, then after, the sum of the resultant coffee in the carafe and the now heavier grounds should equal the weight of the water you poured in.

I'll assume you don't miss and pour water all over like I do.

yes, in the modern age a cup is not a cup. i've seen 6 and 5 ounces called a cup when it comes to coffee. don't understand why or where this malpractice first occurred.

Seems like a good cause for a class action law suit. If lawyers could get Seagate to cave because 1,000,000,000 bytes is not a gigabyte in some peoples minds, it seems like a slam dunk to when a cup is not 8oz.

The "mugs" we call coffee cups these days are a lot larger than what used to be used. You can see it with any older set of china or old place settings of dinnerware. I have some older sets around. The cups hold 8 ounces filled to the rim, or a "cup". You would only put about 5-6 ounces of coffee in to leave room for milk or cream and to not slop it all over.
