I weigh my partially used fuel canisters and compute the remaining fuel. I use 6-12 grams per day depending on how cold the water and air are, if I make coffee, if I have to simmer, etc. This one has 94 grams of fuel left, so it will be more than enough for 5 nights. I'm eating my favorite @mtnhouse Beef Stroganoff with a packet of pepper added 😋
