Daily Water Requirement Formula

Formula
$$\text{Daily Water Intake (L)} = \text{Weight (kg)} \times 0.033$$

Explanation:
A common rule suggests drinking approximately 33 ml of water per kg of body weight (or 0.67 oz per lb). Adjustments can be made based on physical activity, climate, or health conditions.

Proper hydration is essential for digestion, metabolism, skin health, and overall energy. This calculator offers a rough estimate of daily water requirements to help you stay on track with hydration. Athletes, active individuals, or people in hot climates may require more water. You can convert results into glasses, liters, or ounces based on your preference.
