Question: how many ml does 8 glasses of water have?
Answer: For someone eating a diet of 2,000 calories per day, this adds up to 2,000 ml (roughly 64 oz), or eight 8-oz glasses. But the report also declared that much of this water could be obtained from foods you consume. Another probable origin of the 8x8 rule is the work of a nutritionist named Dr. Frederick Stare.
