Water Intake Calculator

ما هو Water Intake Calculator؟

A common rule of thumb is 8 cups (about 2 L) per day, but the actual number varies with body size, activity, climate, and life stage. The most cited evidence-based model is 30-35 ml per kg of body weight, which scales to the person's size. Add a bonus for hot climate (+200-500 ml) and for pregnancy (+300 ml) or lactation (+700 ml).

This calculator returns the result in four units so you can use whichever you prefer: litres, millilitres, US fluid ounces, and the 8-oz (240 ml) cup. The "baseline" is the body-weight × factor number; the adjustments are listed separately so you can see what each part contributes.
