What Is a Water Intake Calculator?

Water Intake Calculator is a simple and effective tool that helps you determine your daily water intake. About 60% of our body is made up of water, so water is essential for every cell, tissue, and organ in the body to function properly.

The main function of this calculator is to advise you on the right amount of water to drink based on your weight, physical activity, and weather. As a result, you can easily know how much water you should drink per day. This is an effective way for those who want to follow the recommended daily water intake.

Why Daily Water Intake Is Important

Drinking water daily is not just to quench your thirst—it is associated with many important processes inside our body. Drinking the right amount of water keeps the body's metabolism healthy, the digestive system works well, and toxins are easily eliminated from the body.

If someone does not drink enough water, dehydration can occur. This can result in dizziness, fatigue, mood swings, and kidney problems. Therefore, ensuring the recommended daily water intake every day is not only part of a healthy lifestyle, but it should become a habit.

Recommended Daily Water Intake by Weight

Water needs vary from person to person, especially based on weight. In general, the daily water intake for an adult is calculated as 30–40 ml of water per kilogram of weight.

For example:

• Weight 50 kg = 1.5 – 2.0 liters of water
• Weight 70 kg = 2.1 – 2.8 liters of water
• Weight 90 kg = 2.7 – 3.6 liters of water

This guideline is very useful for those who are looking for “water intake by weight” or “recommended water intake daily”.
