Daily Water Intake Calculator

Estimate how much water you should drink each day based on body weight and activity level β€” a far better starting point than the generic "8 glasses a day" rule, which has no scientific basis. The output is total fluid in litres, including water from food (typically about 20% of daily intake) and beverages other than plain water.
