Weigh the full and empty canisters and subtract the difference to find out how much fuel is left
Weighing a canister is a quick and simple way to determine how much fuel is left in your stove. It is important to do this at home before heading out on your trip.
First, weigh an empty canister to get the weight of just the metal canister. You can write this number down or memorise it. If you do not have an empty canister, you can figure out its weight by subtracting a full canister's net weight from its gross weight (these numbers are usually printed on the canister).
Next, weigh the partially used canister and write that number down too. Finally, subtract the weight of the empty canister from the weight of the partially used canister. This will give you the weight of the remaining fuel in the partially used canister. You can then compare this number to the net weight listed on the fuel canister to get a sense of whether the canister is half full, a quarter full, etc.
Some other ways to determine how much fuel is left in your stove include floating the canister in a pot of water and observing where the waterline lands, or performing a test at home to find out how much fuel your stove requires to boil a litre of water.

Float the canister in water and use the waterline to estimate how full it is
If you want to know how much fuel is left in your stove canister, one way is to float the canister in water and use the waterline to estimate how full it is. This method is applicable to all canister sizes. It is important to note that this method is not as accurate as weighing the canister, but it can provide a rough indication of the amount of fuel remaining.
- Place the full fuel canister in the water so that it floats upright. You may need to tip the canister slightly while inserting it to let air escape from underneath.
- Take note of where the waterline is on the canister. It can be helpful to look for where the water touches writing or a logo on the canister.
- Remove the canister from the water and mark the spot with a permanent marker.
- Repeat the process with an empty canister, marking the spot where the waterline is.
- Now, take your partially used canister and transfer the marks from the full and empty canisters onto it.
- Place the partially used canister into the water, ensuring that you tilt it to let the air escape.
- Note where the waterline is on the canister and remove it from the water.
- Compare the waterline on the partially used canister to the marks from the full and empty canisters. This will give you an estimate of how much fuel is left in the canister.
It is worth mentioning that some fuel canisters have a gauge printed on the side, so you don't need to make any marks with a marker. Simply put the partially used canister in the water and note where the waterline lands on the gauge. Additionally, newer canisters may have a small pictorial gauge on the side, and the water level will roughly align with the indicators on the side.

Check if the manufacturer has provided a fuel gauge or burn time estimates
If you want to check how much fuel is left in your stove, you can refer to the manufacturer's specifications. Some stoves come with a fuel gauge or burn time estimates. For instance, MSR's IsoPro fuel canisters have a built-in float gauge that determines how much fuel is left in the 4 oz. and 8 oz. canisters. Similarly, Jetboil canisters have a fuel gauge printed on them.
If your stove doesn't have a fuel gauge, you can perform a simple test at home to find out how much fuel your stove requires to boil a liter of water and how long it will burn on a given amount of fuel. You can then calculate how much fuel you will need for your trip.
You can also estimate the amount of fuel left in your canister by using a kitchen scale to weigh a partially used canister and a completely empty one. Then, subtract the weight of the empty canister from the weight of the partially used one to determine how much fuel is left.
Another method to determine the amount of fuel left in your canister is to float the canister in a pot of water. The waterline on the canister will indicate the amount of fuel left by volume. You can then compare this to a full and empty canister to estimate the amount of fuel left.

Estimate how much fuel you'll need based on the amount of water you need to boil
Estimating the amount of fuel you'll need for your stove depends on several factors, including the number of people, the number of hot meals and drinks required, the type of food being cooked, and the environmental conditions. Here are some steps to help you estimate how much fuel you'll need based on the amount of water you need to boil:
Step 1: Determine the Amount of Water Needed per Person per Meal
As a general rule, plan to boil one liter of water per person per meal. This estimate assumes that most meals will involve boiling water, such as for freeze-dried meals, coffee, tea, or instant oatmeal. If some people prefer cold meals or drinks, adjust the amount accordingly.
Step 2: Calculate the Total Water Requirement
Multiply the number of people in your group by the number of meals that require boiling water. This will give you the total number of liters of water you need to boil. For example, if you have a group of four people and plan to have two meals that require boiling water, your calculation would be: 4 people x 2 meals = 8 liters of water.
Step 3: Consider Environmental Factors
Factors such as wind, altitude, and temperature can significantly impact the amount of fuel required. Stoves with exposed burners can use up to three times more fuel in windy conditions. Higher altitudes and colder temperatures can also increase the boil time, resulting in higher fuel consumption. If you anticipate these factors playing a role during your trip, consider adding a safety cushion of 20% to 40% more fuel.
Step 4: Consult Your Stove's Specifications
Refer to your stove's specifications to determine its boil time and burn time. Boil time refers to how long it takes for the stove to bring a specified amount of water to a boil under ideal conditions. Burn time tells you how long the stove can run on a specified amount of fuel. You can use these specifications to calculate the amount of fuel needed to boil your total amount of water.
Step 5: Estimate Fuel Usage
To estimate fuel usage, multiply the total amount of water you need to boil by your stove's burn time. For example, if your stove has a burn time of 60 minutes for 0.5 liters of water, and you need to boil 8 liters of water, your calculation would be: 8 liters x 60 minutes = 480 minutes. This means you would need enough fuel for 480 minutes of burn time.
Step 6: Adjust for Environmental Factors
If you anticipate windy, cold, or high-altitude conditions, consider increasing your fuel estimate. For example, you might decide to add a 20% safety cushion, bringing your estimate to 576 minutes of burn time.
Step 7: Convert to Fuel Weight
Finally, refer to your stove's specifications to determine how much fuel is required for the calculated burn time. This information is typically provided in grams or ounces. If your stove's specifications indicate that 100 grams of fuel provide 60 minutes of burn time, then for 576 minutes of burn time, you would need: 576 minutes / 60 minutes per 100 grams = 9.6 grams of fuel.
By following these steps and considering your specific circumstances, you can estimate how much fuel you'll need for your stove based on the amount of water you need to boil. Remember that this is an estimate, and actual fuel consumption may vary depending on various factors.

Account for environmental factors that may affect fuel usage, such as wind and temperature
When it comes to accounting for environmental factors that may affect fuel usage, wind and temperature are key considerations.
Wind is the most common environmental factor that can significantly impact a stove's performance. Windy conditions can disperse a lot of the heat generated by your stove, leading to increased fuel consumption. The impact of wind varies depending on the stove model. For instance, stoves with exposed burners can use up to three times more fuel in a breeze, whereas stove systems like the JetBoil Flash and MiniMo are more wind-resistant. If you anticipate windy conditions and your stove doesn't have an in-built windscreen, consider bringing a separate windscreen to shield your stove from the wind. This can help you save fuel. However, be mindful that windscreens add a bit of weight to your pack.
Temperature also plays a crucial role in fuel usage. Cold temperatures cause a drop in canister pressure, affecting fuel efficiency. In colder conditions, water takes longer to boil, resulting in extended stove usage and higher fuel consumption. Additionally, cold temperatures impact the fuel canister itself, and it's recommended to place the canister in warm water before use to improve performance. The type of stove also matters in cold temperatures. Liquid fuel stoves, for example, may suffer from instant frostbite issues, making white gas stoves a more suitable option for extreme cold.
Other factors that can influence fuel usage include elevation, meal preparation methods (simmering, boiling, etc.), and the number of meals cooked. At higher elevations, water boils faster, but raw food cooks slower. Simmering and preparing meals that require prolonged boiling, such as pasta or melting snow, will increase fuel usage. Therefore, it's important to consider the types of meals you plan to cook and adjust your fuel calculations accordingly.
While it's challenging to predict the exact impact of these environmental factors on fuel usage, it's advisable to err on the side of caution. When faced with extremely windy or cold conditions, consider doubling your fuel supply compared to what you would bring in perfect conditions. Additionally, pay attention to your stove's performance and fuel usage in different conditions, as this will help you make more informed decisions for future trips.
