# SAT / ACT Prep Online Guides and Tips

Research suggests that there are numerous health benefits to drinking water, including increased energy, weight loss, improved skin complexion, and more. Water's many benefits are well-known and often touted, but how much water should we actually aim to drink in a day?

One common recommendation is to drink a gallon of water in a day. In this article, I'll cover how many glasses in a gallon for standard and non-standard glasses and talk about how many glasses of water in a gallon you should actually drink each day.

## How Many Glasses in a Gallon: Standard Glass

A gallon contains 128 ounces. A standard glass contains eight ounces. So, one gallon equals 16 eight ounce glasses of water.

## How Many Glasses in a Gallon: Non-Standard Glass

Other common types of glassware include pint glasses, which normally hold 16 ounces, or smaller, lowball glasses which hold between four to eight ounces, depending on the glass.

Since a pint glass holds 16 ounces, and a gallon is 128 ounces, one gallon equals eight pint glasses.

A gallon holds 32 4-ounce lowball glasses, approximately 21.3 6-ounce lowball glasses, and 16 eight ounce lowball glasses.

In order to find out how many glasses of a particular size are in the gallon, you can divide 128 (the number of ounces in a gallon) by the number of ounces your glass holds.

## How Much Water Should You Drink in a Day?

Now that we know how many glasses of water are in a gallon, let's discuss how much water you should drink a day.

The Mayo Clinic recommends that average, healthy adults living in temperate climates drink eight standard glasses of water a day, which is half of the 16 standard glasses of water that make up a gallon.

If you're extremely active, dehydrated, or live in a more arid part of the world, you'll want to increase the amount of water you consume every day. People who sweat a lot are more likely to need to drink a gallon of water every day than people who have a normal, moderate activity level.

The bottom line—you should aim to drink at least eight glasses of water every day to receive health benefits such as increase hydration, better sleep, and more. If you're highly active, consider upping the amount of water you consume to one gallon to replace the fluids you lose while sweating.
