How the Backpack Weight Percentage Calculator works
Pack percentage = pack weight ÷ body weight × 100. A common guideline is to carry no more than about 20 percent of your body weight on a multi-day trip, and 10 to 15 percent or less for children, older hikers, or long days. Weigh the pack with water and food included, because those are the heaviest changing items. This is a planning guide, not a medical limit. Example: with Your body weight 70 kg, Loaded pack weight 12 kg, and Recommended maximum 20 %, the result is Pack as % of body weight = 17.14%; Recommended maximum pack weight (kg) = 14; Weight to remove to reach the limit (kg) = 0.
