We have designed the MercatorGear Gas Canister Calculator to help you calculate the optimal number of canisters you will need for your trip or expedition.
The calculator tells you how many gas canisters you will need depending on the number of days on the the trail, number of people, your hot water requirements and type of stove.
You can also select the size of gas canister you take. For example, a short one-person expedition may require only a small 110g gas canister. A longer expendition with plenty of cooking will save weight by taking larger 450g gas canisters.
By changing the various parameters, the calculation updates until you find the best combination of stove type and gas canister for your particular expedition.
