health.hydration-sports Calculator
Calculates sweat rate, fluid replacement volume, and recommended electrolyte intake for a sports session from pre/post weights and session duration. Athletes should drink to replace 75–80% of sweat losses — overdrinking (hyponatraemia) is riskier than mild dehydration.
Inputs
Weight
Body or object weight. For health calculators, usually in kg or lbs.
Duration Hr
Length of time the process lasts. Ensure units are consistent with rate inputs.
Intensity
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Temp C
Reference formula or conversion factor shown for context.
Results
sweat loss (L)
The decrease or degradation from the baseline.
fluid replacement needed (L)
Sample size or count used in the calculation.
daily baseline (L)
Sample size or count used in the calculation.
total daily target (L)
The combined total across all inputs and components.
sweat rate (L/hr)
The value at the specified point or condition.
electrolytes
Reference formula or conversion factor shown for context.
