Daily Water Intake
Evidence-based hydration targets for your weight and activity — especially relevant to accurate weigh-ins and tape tests.
Formula
Common target: 0.5–0.7 oz per lb of body weight, plus extra for sweat.
Healthy range
~91–125 oz/day for most adults (IOM); higher in hot climates and training.
Military & first-responder angle
Dehydration can falsely lower your scale weight at a weigh-in and affect performance on the ACFT or CPAT. Hydrate normally the day before any assessment.
Calculator
General daily water-intake range by body weight (IOM basis, ~30–35 ml/kg).
