Daily Water Intake Calculator: How Much Should You Drink?
We've all heard the advice "drink 8 glasses of water a day," but is that scientifically accurate for everyone? Not really. Your water requirement depends on your unique body weight, climate, and activity level. Our Hydration Calculator helps you find the exact amount of water you need to stay healthy and fit.
The Science: Weight vs. Water
Medical experts suggest that water intake should be proportional to your body mass. A general rule of thumb used by nutritionists is:
Body Weight (kg) ÷ 30 = Liters per Day
For example, if you weigh 60 kg, you need approx 2 liters. If you weigh 90 kg, you need 3 liters.
Does Activity Level Matter?
Yes, significantly! If you workout in the gym or have a field job in the Indian summer, you lose water quickly through sweat. You need to add approximately 0.5 to 1 liter extra for every hour of intense activity to prevent dehydration.
