Practical Example

Imagine you’re a 70 kg hiker preparing for a trip:

• Body weight: 70 kg
• Items added:
  • Tent: 2.5 kg
  • Sleeping bag: 1.8 kg
  • Water bottle: 1.2 kg
  • Food supplies: 3.5 kg
  • First aid kit: 0.7 kg

Total Backpack Weight = 9.7 kg

• That’s about 13.8% of your body weight.
• The recommended maximum load for 70 kg is 17.5 kg (25%).
• Result: ✅ Safe to carry, well within the limit.

If the same person adds more gear totaling 20 kg, the tool will warn that the backpack is overloaded and could increase the risk of strain or injury.
