How is Your Water Requirement Calculated?
This calculator estimates your recommended daily water intake based on your body weight. The general guideline is:
- 33 ml per kilogram of body weight (0.033 L/kg)
- Equivalent to roughly 0.5 oz per pound of body weight for imperial units
Additional Adjustments:
- Activity: Physical activity increases hydration needs
- Climate: Hot environments require higher fluid intake
Note: Fluid intake also includes water from food and other beverages.
Disclaimer: This is a general recommendation. Always consult a healthcare provider for personalized hydration advice.
