Daily Water Intake Calculator
Water Intake Calculator – Calculate Your Daily Hydration Needs
A Water Intake Calculator is a health and fitness tool used to estimate how much water a person should drink daily. Water is essential for digestion, circulation, temperature regulation, and overall health.
This online Water Intake Calculator estimates your daily water requirement based on body weight and activity level. It avoids generic advice and provides personalized hydration guidance.
Why Daily Water Intake Matters
The human body is composed of approximately 60% water. Even mild dehydration can lead to fatigue, headaches, reduced concentration, and physical weakness.
Proper hydration supports metabolism, joint lubrication, nutrient transport, and waste removal.
Is the “8 Glasses a Day” Rule Accurate?
The popular “8 glasses a day” rule is an oversimplification. Water needs vary widely based on body size, activity, climate, and lifestyle.
This calculator uses a weight-based approach, which is more accurate for most individuals.
How Water Intake Is Calculated
This calculator uses a commonly accepted guideline:
Base Water Intake = 35 ml × Body Weight (kg)
The result is then adjusted based on activity level. Active individuals lose more fluids and require more water.
