8 x 8 oz: This is the standard answer but must be tempered by reason.If you are working outside in the heat you may well need 8 liters (think quarts) per day.As a former dr with the usmc i suggest you look at your urine.If it is deep yellow you are behind(no alcohol nor caffeine which are diuretics and cause you to dump water).Urine color is easy, quick and easy.If you are not peeing-you are way behind!
