Water Intake Calculator
This water intake calculator estimates your daily water needs based on your weight and activity level. Staying hydrated is essential for health, and this tool provides personalized recommendations to help you maintain proper fluid balance.
How the Water Intake Calculator Works
The calculator uses a formula based on body weight: multiply your weight in kg by 30-40 ml per kg, depending on activity level. Sedentary people use 30 ml/kg, moderate 35 ml/kg, and active 40 ml/kg. This gives daily water intake in liters, including all fluids.
Steps to Use
- Enter your weight in kilograms.
- Select your activity level.
- Click "Calculate Water Intake" to see your daily recommendation.
Accuracy and Limitations
This is a general estimate and may not account for climate, health conditions, or individual needs like pregnancy. Actual requirements can vary; factors like sweat loss or illness increase needs. Consult a doctor for personalized hydration advice, especially if you have medical conditions.
