🎒 Backpacking Food Weight Calculator

Because food weight significantly affects total pack weight on multi-day trips, backpackers commonly plan around 0.6–1.1 kg per person per day (weight of dehydrated meals, bars, etc.). Light activity typically targets ~0.6kg/day, moderate activity ~0.8kg/day, and high-exertion or cold-weather trips with higher calorie burn ~1.0–1.1kg/day. For example, 2 people on a 4-day moderate-activity trip need 4 days × 0.8kg × 2 people = 6.4kg total.

Total food weight = Days × Per-person daily weight (kg) × Number of people

For reference, typical backpacking calorie burn is commonly cited around 2,500–4,500 kcal/day depending on exertion — this range is informational only and is not used directly in the weight calculation, since calorie density varies widely by food type and would make a weight-from-calories conversion unreliable. When planning meals, favor calorie-dense dehydrated foods and nuts to hit your target weight efficiently.
