How to Calculate Your Fluid Loss

Calorie/ minute =(3.5 x EF x Body weight x Heart rate factor) / 200

Heart rate factor: 0.95, HR < 65% Max. HR 1.0, HR = 65-85% Max. HR 1.05, HR > 85% Max. HR

EF: Exercise Factor (2-20)

Body Weight in kg: 30-250kg or 50-500lbs (1kg = 2.21lbs)

Fluid Loss (Ounce) / Hour = (Kcal Per Hour * T + H

2) / 1450

T: Temperature in oF

H: Humidity in percentage
