It's 64 fluid oz, which is half a gallon, which is 1.89 liters, I believe.

8 Glasses Of Water In Oz

The actual figure is 8 x 8 ounces glasses.

The reason they suggest eight glasses a day is to remind you to drink water on a regular basis. To be realistic, 64 ounces is actually not enough water.

On a given day if you're not doing much, you should probably drink at least 1 liter every 2-3 hours. If you're active, and especially outside in the sun, or working out, you should drink about 1 liter every hour to hour and a half.

I'm a medic in the army, and on 64 ounces of water a day, most of my guys couldn't even do their job without dehydrating.

The rough estimate of 8 glasses a day is just to remind you to drink water. Things like soda, tea, and so on will help hydrate you, but nothing beats good old water.

Even if you're only slightly dehydrated your performance at any given task can be severely reduced. A lot of people who experience tiredness all day, or sluggishness, are often chronically dehydrated (In fact, most people are...because most people hardly drink any water).

Try to drink a good sized glass of water every hour or two, and you should be ok. Drink more before doing excercise, hard work, or going into the sun. It takes several hours for water drank to really hydrate your body, so once you're thirsty you're already a little dehydrated.

Make sure you're eating too. Drink too much water and you can flush electrolytes (Potassium and Magnesium) and vitamins from your system. This is called overhydration, and can lead to feeling crappy overall, as well as sluggishness and such. If you've been drinking a lot of fluids, and feel kind of dehydrated, eat something. Your body needs it's vitamins, electrolytes and sodium (Salt). It all works together!

Hope this helps!

8 glasses of water is 64 oz's or 1/2 gallon. A glass of water is 8 oz. Not the typical 12 oz glass in every normal household. And you spread those 8 glasses of water throughout your normal waking day.
