Mugs vary too much.
A cup of coffee is 5oz. I average 4 cups per day. Black.
well most average sized home mugs/cups are 4-6ish
The standard "coffee mug" holds 10oz.
whatever bro, you know that I know that you know I know the average home cup/mug is average. For clarity sake we will now standardize the home mug as a a large shot from a kuerig machine.
