**QUESTION**: What do the numbers mean on a Mr. Coffee maker? I’m visiting my inlaws and they have a different machine than I am used to and I want to make coffee. — Erika F

**ANSWER**: You see in the photo above that there are number marks on the coffee pot, and also number marks on the Mr. Coffee maker itself where you add water. Those **numbers represent “coffee cups.”** While **most bags of coffee describe a “cup of coffee” as 6 ounces**, the **Mr. Coffee maker calls a cup of coffee just 5 ounces**. So you’ll need slightly less ground coffee in the machine than they sometimes describe on the back of a bag of coffee.

Want to just make a full pot of coffee with a 12 cup Mr. Coffee maker? Then simply fill up the clean, unused pot to the mark that says 12 with clean, cold water and pour it into the machine. When you do that, you’ll see that it hits the same mark 12 on the coffee machine.

Then you simply add 11 tablespoons of ground coffee into a the filter and you’ll be able to make a full pot. If you’re using the Mr. Coffee scoop that comes with the coffee maker, use 5 1/2 scoops from the Mr. Coffee scoop. A standard coffee scoop is 2 tablespoons. So 5 1/2 scoops is the same as 11 tablespoons.

Want to learn about how much water and coffee you need for different amounts? Here’s what Mr. Coffee says about it in their instructions for one of their 12 cup coffee makers.

## When is a Cup not a Cup?

A cup of liquid is 8 ounces of liquid. But when you are talking about coffee cups, it’s a different amount! Many **coffee makers like OXO and Mr Coffee describe a cup of coffee as 5 ounces**.

And of course if you have a giant mug or a big insulated steel cup that you take with you, those will often hold 14 to 24 ounces.

To put it in perspective a different way, a tall coffee at Starbucks is 12 ounces, a grande is 16 ounces and a venti is 20 ounces.

That’s why you’ve probably noticed that when you make a full pot of coffee that says “12 cups” you often run out pretty quickly after you have only filled up a few mugs. A **full 12 cup pot of Mr. Coffee only holds 60 ounces**. So you could potentially fill up just two big stainless steel mugs and use almost the entire pot!

If you’re brewing coffee for a group of people, it’s always safer to just make a full pot in case you are pouring into large mugs.
