Water is one of the most essential elements in life necessary for survival. Knowing how many ounces are in a bottle of water can help you measure the necessary fluid intake you need to stay hydrated and healthy. Knowing this useful information can also help you calculate and compare the cost of purchasing water or how much you will need for certain activities.

Common Bottle Sizes

Bottled water usually comes in a variety of sizes, ranging from 8-ounce bottles to as high as 128-ounce bottles. This size difference can be attributed to the intended use of the bottle and the amount of liquid needed for the purpose. Here are a few of the commonly seen sizes.

• 8-ounce bottled water – typically seen in different activities such as stocking a mini-fridge or sports drinks.
• 16.9-ounce bottled water – these bottles are known as one-liter bottles and is the standard single-serving size that you usually see in vending machines and supermarket shelves.
• 20-ounce bottled water – this size is often used for single servings and marketed as “jumbo-sized” .
• 64-ounce bottled water – this size bottle is often used for refilling your water bottle more than once.
• 128-ounce bottled water – this size is typically for situations where more water is needed such as a sports team drinking from one bottle.

Measuring Water Volume Based on Ounces

Once you know how much of each size of water bottles contains in ounces, you can easily compare and figure out the volume of water you want to purchase. Here are the conversions:

• 1 liter or 33.8 fluid ounces equals 1.32 large bottles.
• 1 large bottle of 16.9oz equals 11.83 ounces.
• 1 jumbo bottle of 20oz equals 15.83 ounces.
• 1 large bottle of 64oz equals 51.2 ounces.
• 1 jumbo bottle of 128oz equals 103.6 ounces.

Summary

Knowing how many ounces are in a bottle of water is important for keeping track of your water intake, mindful of your liquid needs for certain situations, and for saving money when buying water. It’s also important to note that a safe limit for water intake daily is up to 64 ounces for an adult, so try to not exceed that limit.
