Water Intake Calculator (UAE)
Calculate your daily water requirement in ounces and liters based on body weight, activity, and climate. Science-based hydration targets.
How Much Water Do You Actually Need?
Water is the fundamental solvent of human biology, regulating body temperature, lubricating joints, delivering nutrients to cells, and facilitating kidney function. Hitting your daily hydration targets is crucial for health and physical performance.
Your fluid requirements depend on your weight, activity levels, climate, and overall health. As a general baseline, health experts recommend consuming half your body weight in ounces of water per day. Active individuals should add 12 to 20 ounces for every 30 minutes of exercise.
Mild dehydration can cause fatigue, headaches, decreased physical strength, and false hunger cues. Tracking your water intake using our calculator ensures you maintain optimal cellular hydration throughout the day.

Q: Does coffee count toward water intake?
Yes, caffeinated drinks and food moisture do contribute to your total hydration, though pure water remains the best source.
