Formula
A common clinical planning estimate is 35 ml for each kilogram of body weight:
Milliliters = kilograms × 35
Food also contains water. This page does not subtract food moisture or add extra for exercise and heat.
Assumptions
- The rate is 35 ml per kg.
- The result is a planning volume, not a required prescription.
Worked example
70 kg at 35 ml/kg is 2,450 ml.
Input definitions
- Weight
- Body weight in kilograms.
Limitations
This is an informational estimate for adults. It is not a diagnosis, a diet plan, or a training prescription. Pregnancy, illness, and medication can change what is appropriate.
Questions
Should everyone drink this amount?
No. Climate, activity, and medical conditions change fluid needs. This is only weight times 35 ml.
Does coffee count?
The page does not classify drinks. It only multiplies weight by 35.
