Sweat Rate Calculator.
Estimates your sweat rate in liters per hour based on pre- and post-exercise body weight, fluid intake, and exercise duration.
Ihre Eingaben
So funktioniert es
- 1
Weigh yourself immediately before exercise, wearing minimal clothing.
- 2
Record your weight after exercise, towel-dried, with the same clothing.
- 3
Note the total fluid you consumed during the session in liters.
- 4
Subtract post-weight from pre-weight, add fluid intake, then divide by hours exercised.
((pre_weight - post_weight) + fluid_intake) / (duration / 60)Häufig gestellte Fragen
Why do I need to account for fluid intake?
Because you lose water through sweat, but drinking replaces some of it. Adding intake gives the true total sweat loss.
What if I used the bathroom during exercise?
For accuracy, avoid bathroom breaks or adjust for urine loss. Otherwise, the estimate may be slightly off.
How can I use my sweat rate?
Use it to plan hydration: drink roughly the same amount per hour during similar workouts to maintain fluid balance.

Formeln
Die Mathematik hinter diesem Rechner, aufgeschrieben, damit Sie das Ergebnis überprüfen können.
Sweat Rate
This formula estimates how much fluid you lose per hour through sweating, combining weight change and fluid consumed.
Example:
Input: Pre=70kg, Post=69.2kg, Intake=0.5L, Duration=1h
Calculation: (70 - 69.2 + 0.5) / 1 = 1.3
Result: 1.30 L/h
Anwendungsfälle im Alltag
Wo diese Berechnung im täglichen Leben vorkommt.
Hydration planning
Know your sweat rate to determine how much to drink during training or races.
Example: If you sweat 1.2 L/h, aim to drink about 1.2 L per hour.
Monitoring dehydration risk
Track changes in sweat rate over time to spot overhydration or dehydration patterns.
Example: A sudden drop may indicate heat acclimatization or illness.
Customizing nutrition strategy
Combine sweat rate with electrolyte needs to tailor sports drinks.
Example: High sweat rates may require extra sodium.
Tipps und häufige Fehler
Tips
- Weigh yourself on the same scale for consistency.
- Use the same clothing or subtract its weight for accuracy.
- Record fluid intake in liters, not cups, for precise math.
- Perform the test under similar conditions (temperature, intensity) for reliable data.
Common Mistakes to Avoid
- Forgetting to include fluid intake, which underestimates sweat loss.
- Using duration in minutes without converting to hours.
- Weighing at different times of day or with different clothing.
Annahmen und Einschränkungen
- Use the stated inputs and units.
- Results are estimates for planning and education.
- Check measurements and source data before making an important decision.
