A canister stove uses about 0.35 oz of fuel per boil. With 3 boils per day for a 4-day trip, you need about 5.5 oz — one 8 oz canister is sufficient with a buffer.
| Stove Type | Oz/Boil | 4 Days (3x) | Canister |
|---|---|---|---|
| Canister | 0.35 oz | ~5.5 oz | 8 oz can |
| Alcohol | 1.0 oz | ~15 oz | Bring bottles |
| White Gas | 0.4 oz | ~6 oz | 11 oz bottle |
Yes. Water boils at lower temperatures at altitude but takes the same energy. Cold and wind increase fuel use. Above 5,000 ft, add 10% per additional 5,000 ft.
Below 32°F, canister fuel pressure drops and burn efficiency decreases by about 15%. White gas stoves perform better in cold than canister stoves.
One boil is heating roughly 0.5 liters (2 cups) of water to a rolling boil. A typical freeze-dried meal needs one boil. Morning coffee or tea is another boil.
