How Many Cups are there in a Bottle of Water?

So many experts and health sites are publishing their recommendations for how much water we should be taking in each day. These recommendations are usually also measured in cups. Because of this, many people have found it quite challenging to determine just how much water they are getting in a day and whether or not they are actually getting enough to meet their daily needs.

Adding to the challenge is the fact that water bottles come in different sizes – plus the fact that it can be hard to determine or know for sure what the capacity of one “cup” is when it comes to these research results and advice.

Generally, health recommendations for cups of water needed per day are quite vague and unspecific when it comes to actual measurements. They are not in themselves very scientific, though they are based on scientific findings of the human body and what it needs.

Hence, with a little bit of research and mindfulness, we can use these recommendations as a guide when it comes to making sure we’re drinking enough water per day.

How Many Cups of Water Can Fill a Bottle?

There are several factors that determine how many cups exactly are in a bottle of water. Two of the most important ones are cup size and water bottle size.

Cup Size

Generally speaking, when health experts refer to “cups of water,” they are referring to an eight-ounce glass. Keep this in mind as we discuss, and keep it in mind also every time you encounter recommendations of this nature.

Another popular, though some say a little outdated recommendation, is to take in eight glasses of water each day. If you go by that rule, then a great way to remember this is to think: 8×8. That is eight 8-ounce cups, which is equivalent to around 2 liters or half a gallon.

However, we are talking about water intake in terms of water bottle sizes. So let’s go right ahead and figure it all out!

Water Bottle Size

The second important factor that we have to remember when it comes to figuring out how many cups are in a water bottle is the size of the water bottle in question. There are many different sizes of water bottles available:

  • 16 ounces or 16.9 fl oz is the standard size
  • 20 ounces
  • 24 ounces
  • 32 ounces

Now, the number of cups of water you are drinking each time you empty out your water bottle depends on the actual size of the water bottle.

Conversion

To find out how many cups of water are in a bottle of water, all you need to do is this:

Just divide the water bottle size by 8.

The equation would be:

(Water bottle size in ounces) / 8 ounces = the number of cups in that water bottle

Using this equation, the following applies:

  • A 16-ounce bottle contains about 2 cups of water
  • A 20-ounce bottle contains 2.5 cups of water
  • A 24-ounce water bottle contains 3 cups of water
  • A 32-ounce water bottle contains 4 cups of water

You can use the equation for other sizes of water bottles as well.

As you can see, there will be varying answers to the question of how many cups of water are in a water bottle.

Am I Emptying My Water Bottle Enough?

We can give you an idea about your water consumption by applying our conversion to the 8×8 method. After converting how many cups of water your water bottle can hold, you can then see how many times you need to refill and empty out your water bottle to at least hit the 8 glasses a day goal.

The basic equation would then be:

8 / [(Water bottle size in ounces) / 8 ounces] = number of water bottles you should empty in a day

Using that thought process, let’s examine some of the more common water bottle sizes:

  • 16-ounce water bottle = 2 cups
  • 8 / 2 = 4 16 ounce water bottles in a day
  • 20 ounce water bottle = 2.5 cups
  • 8 / 2.5 = 3 ¼ 20 ounce water bottles in a day
  • 24 ounce water bottle = 3 cups
  • 8 / 3 = 2.6 24 ounce water bottles in a day
  • 32 ounce water bottle = 4 cups
  • 8 / 4 = 2 32 ounce water bottles in a day
