Is 1 cup a mug?
There is a Difference in Details
A mug typically holds around 10-12 ounces, while a cup holds 8 ounces. So, when it comes to coffee, a mug is the better choice if you want a larger serving. And if you need to carry your coffee with you, a mug is the way to go.
Is a mug 2 cups?
I dug around a little, and a standard-size coffee mug starts at 8 oz. (1 cup). The most common standard mug size is 11 oz., though capacities vary greatly. 14 to 15 oz. is the next most common size but they can go up to 20 to 25 oz.
What measure is a mug?
Note that standard coffee mugs range in size from about 8-12 oz (237-355 mL). Some state the size on the bottom. If you aren't sure how big your coffee mug is, use a 12 oz (355 mL) bottle of water to figure it out.
