health.sweat-rate-hydration Calculator
Calculates sweat rate from pre- and post-exercise body weight and fluid intake, and determines the hourly fluid replacement target. Sweat rates above 2 L/hour are common in hot weather team sports — maintaining hydration above 2% body weight loss preserves performance.
Inputs
Pre Exercise Weight Kg
Body or object weight. For health calculators, usually in kg or lbs.
Post Exercise Weight Kg
Body or object weight. For health calculators, usually in kg or lbs.
Fluid Consumed L
Reference formula or conversion factor shown for context.
Exercise Duration Hr
Length of time the process lasts. Ensure units are consistent with rate inputs.
Results
sweat rate (L/hr)
The value at the specified point or condition.
total sweat loss (L)
The combined total across all inputs and components.
net dehydration (% body wt)
The proportional relationship between two quantities.
performance impact
The specific form or variant of the result.
rehydration target
The proportional relationship between two quantities.
