Water intake by body weight
How much water should you drink at 190 lb?
Quick answer
At 190 lb (86 kg), the water intake calculator's rule of thumb gives about 2.8 litres (96 oz, 12 cups) a day without exercise in a temperate climate. An hour of exercise in a hot climate takes it to about 3.9 litres (132 oz). It is a planning estimate, not a medical recommendation.

Work it out for your own weight
Every figure here comes from the water intake calculator: 33 ml per kilogram of body weight (86 kg × 33 ml = 2.84 litres before rounding), plus 350 ml for every 30 minutes of exercise, plus 10% in a hot climate, rounded to the nearest 10 ml. Use it to enter your own weight in kilograms or pounds, your minutes of exercise and your climate.
It is a rule of thumb, and there is no single official requirement. The calculator counts water from food and other drinks as well as from the glass.
How 2.8 litres compares with the reference intake
The Institute of Medicine's Adequate Intake of total water, from all drinks and all food, is 2.7 litres a day for women and 3.7 litres for men aged 19 to 30. The 2.8 litres for 190 lb is above the women's figure and below the men's. About one fifth of total water intake comes from food, according to the same report, so the glass is not the whole of it.
