Water Intake guide
What it is for
The Water Intake provides a planning estimate from the information entered.
How it is calculated
The implemented rule is daily fluid ounces = body weight in pounds × 0.5. It is a rough planning rule, not a personalized hydration prescription.
Assumptions
It assumes the inputs use the requested units and represent a general reference population, not an individual assessment.
Example
For 150 lb, the displayed estimate is 75 fl oz/day. Climate, exercise and medical restrictions can make this rule inappropriate.
Limitations
This is an educational estimate, not a diagnosis, treatment, or dosing instruction. Consult a licensed healthcare professional, particularly during pregnancy, with symptoms, or before changing health behavior.
