Daily Water Intake by Weight
This table uses exactly the same formula as the main calculator: weight (kg) × 35 ml for adults, plus 700 ml for moderate activity, or 1,400 ml activity + 350 ml hot climate for the athlete / hot climate column. Choosing very hot climate (700 ml) in the calculator will therefore give 350 ml more than this column. Values are for an adult aged 18–55 in a moderate climate, with no pregnancy or breastfeeding adjustment.
