Water Intake Calculator
The Water Intake Calculator gives you an approximate amount of water you need to consume daily to avoid dehydration. By providing inputs like full body weight and workout duration in the selected unit system, you can easily calculate the daily water intake result in no time.
What is the Importance of Water Intake?
For good health, you need to drink enough water every day. Dehydration can cause confusion, cause mood changes, and cause your body to overheat. Besides helping to make saliva, water intake regulates your body temperature and protects the tissues, spinal cord, and joints.
Water intake helps expel waste through perspiration, urination, and defecation, and it helps fight off illnesses. Consuming adequate amounts will have two benefits: not only will you maintain your current state of health, but also you may improve it.
Factors Important For Calculating Water Intake
Water and other fluids can keep healthy people hydrated. For some people, drinking up to eight glasses of water a day might be enough to stay hydrated. But other people may need more. Factors that are important for water intake are as follows:-
- Exercise: If you do any exercise that causes you to sweat, make sure you drink extra water to replace the fluids you're losing. You have to consume water before, during, and after exercising.
- Environment: Hot and humid weather can make you sweat and cause you to drink more fluids, and altitude can also cause dehydration.
- Pregnancy and breast-feeding: During pregnancy and while breastfeeding, you may need to drink more fluids.
- Illness: Drink more water if you have a fever, vomiting, or diarrhoea. Other conditions that might require increased fluid intake are urinary tract infections and bladder stones.

How to Determine Water Intake by Weight Manually?
The simple steps for calculating how much water you need to consume on a daily basis is provided here:
- Determine Your body weight.
- Multiply your body weight by 2/3.
- The determined value is water you need to drink on a daily basis.
- Calculate your engagement in work out or exercises. (Add an additional 12 ounces of water for every 30 minutes of exercise)
- Add both the units to calculate the total amount of water you should consume.
- Finally, the determined value is the total Water Intake requirement for your body.
Solved Example on Calculation of Water Intake
Example:
The total bodyweight of Joe is 180 pounds and he spends 100 minutes every day in exercise. Calculate the water intake requirements for Joe.
Solution:
Given, The weight of Joe = 180
The calculation will be as follows:
180× 2/3 = 120 ounces (3.55 liters) of water per day.
Since he spends minutes every day in exercise.
Thus, additional water intake requirement per day = 100 / 30 × 12 = 40 ounces of additional water per day.
Thus, the total water intake requirement will be:
120 ounces + 40 ounces = 160 ounces (4.73 liters) of water per day.
