Calculate Your Daily Water Intake
Why is Water Important?
Water is a vital component of the human body and plays a key role in digestion, circulation, temperature regulation, and nutrient absorption. Proper hydration is necessary for optimal physical and mental performance.
How Water Intake is Calculated
A common guideline is that adults should drink about 35 ml of water per kilogram of body weight. Activity level can increase this requirement.
Example Calculation (Step-by-Step)
Example:
- Body weight = 70 kg
- Water requirement = 35 ml per kg
- Activity level = Normal
Step 1
Multiply body weight by water requirement:
70 × 0.035 = 2.45 liters
Step 2
Daily water intake recommendation:
2.45 liters per day
This means a person weighing 70 kg should drink approximately 2.4–2.5 liters of water per day.
Recommended Daily Water Intake by Weight
| Weight (kg) | Water Intake (Liters) |
|---|---|
| 50 | 1.75 L |
| 60 | 2.1 L |
| 70 | 2.45 L |
| 80 | 2.8 L |
| 90 | 3.15 L |
