Backpacking Stove Fuel & Canister Planner

Estimate fuel from your own stove and conditions instead of assuming one universal burn rate. Calibrate with a real boil when you can, scale for planned water volume and meals, then add the reserve you choose.

Planning estimate only. Stove efficiency changes with wind, temperature, altitude, pot shape, fuel blend, simmering and technique. Carry decisions are yours; do not treat the result as a guarantee that a stove or canister will last.

1. Trip & calibration

Best input: weigh the canister before and after a typical boil on your own stove.

Why calibration beats a generic “grams per boil” number

Two hikers can use the same nominal stove and get very different fuel consumption because one cooks in wind, one uses a wider pot, one simmers and one only boils. A before/after canister weight from a representative boil gives you a better starting point than a universal internet number.
