The formulas to calculate the pack weight for hiking are:
DHPW=0.10×BW
LHPW=0.20×BW
Where:
In order to preserve energy and avoid injury, a day hiking pack should not exceed more than 10% of your body weight, and a longer backpacking hike should not exceed 20% of your body weight. Higher weights than recommended above could lead to injury or burnout.
Let's assume the following value:
Using the formulas to calculate the pack weights:
DHPW=0.10×150=15 lbs
LHPW=0.20×150=30 lbs
The pack weight for a day hike (DHPW) is 15 lbs, and for a long hike (LHPW) is 30 lbs.
