Fellow paddlers and campers.
For those outdoor adventurers who use gas canister stoves and lanterns, it can be difficult to know how much gas is left in a partially used canister.
Please see below a chart I made to show the amount.
You will need access to a small weigh scale which measures ounces or grams.
Canister fuel chart:
Small canister full = 7.4 oz / 210 grams
Small canister empty = 3.5 oz / 100 grams
Large canister full = 13.1 oz / 372 grams
Large canister empty = 5.3 oz / 150 grams
