When planning a camping trip, it's important to consider how much fuel you'll need for cooking. The amount of fuel required will depend on several factors, such as the number of people, the type of meals being cooked, the efficiency of your stove, and the weather conditions. As a general rule, you should plan to boil around one liter of water per person per meal, taking into account whether you'll be simply boiling water or simmering food, which requires more fuel. Wind can also impact fuel usage, as it can prevent heat from reaching your pot or pan, leading to longer burn times. To calculate your fuel needs precisely, you can test your stove at home by boiling a liter of water and weighing the fuel canister before and after. Additionally, consider the boil time and burn time specifications of your stove. For a six-day camping trip, it's advisable to bring more than one small canister or a single large canister to ensure you have enough fuel for your cooking needs.

What You'll Learn
Boiling water: how much you need and how long it takes
When it comes to camping, the amount of fuel you'll need depends on several factors, including the number of people, the duration of your trip, the type of food you'll be cooking, and environmental conditions like wind and altitude.
As a general rule, plan to boil one litre of water per person per meal. This rule assumes you'll be using boiling water to prepare freeze-dried meals, coffee, tea, instant oatmeal, etc. If your meals require simmering (e.g., pasta) or purifying water, you'll need to bring more fuel, as simmering requires a longer burn time.
To estimate the fuel required for your camping trip, you can calculate the total amount of water you'll need to boil and then refer to your stove's specifications for boil time and burn time. For example, if your stove takes 3 minutes to boil one litre of water, and you need to boil 2 litres of water, you'll need 6 minutes of boil time.
Keep in mind that environmental factors will impact your fuel efficiency. Wind can significantly affect your fuel usage, as it prevents heat from reaching your pot or pan, requiring a longer burn time. If you're camping in windy conditions, consider bringing twice as much fuel, especially if you can't block the wind. Additionally, higher altitudes will also increase the time it takes for water to boil.
To be precise about your fuel needs, you can conduct a test at home. Fill your cup or pot with the amount of water you typically use for a boil and use the same stove you plan to bring on your trip. Keep variables such as altitude and ambient temperature consistent. Boil the water for the same duration you would on the trail (at least a 1-minute rolling boil at lower altitudes). The difference between the initial and final weight of your fuel canister will tell you how much fuel a single boil consumes.
For a solo weekend backpacking trip, a small 100g canister of stove fuel is typically sufficient. However, if you're going on a longer trip or have a larger group, you'll need to adjust your fuel supply accordingly. Based on anecdotal evidence, one large fuel canister was enough for one person's three full meals a day for six days, with some fuel left over. In contrast, another camper used a single canister for two 4-day solo trips with warm breakfasts and dinners and coffee twice a day.
To summarise, to determine how much fuel you need for boiling water while camping for six days, consider the number of people, your meal plan, and environmental factors. As a rule of thumb, plan for one litre of boiled water per person per meal, and adjust upwards if simmering or purifying water is required. Test your setup at home to understand your stove's performance, and always bring a little extra fuel to be safe.

Simmering food: requires more fuel than boiling
When planning a camping trip, it is important to consider how much fuel you will need, especially if you are going to be cooking your meals. While a general rule of thumb is to estimate boiling one litre of water per person per meal, there are several factors that can impact your fuel usage. One of the key factors is whether you will be simply boiling water or simmering food.
Simmering food requires more fuel than boiling water alone. This is because simmering involves maintaining a lower, more consistent temperature over a longer period of time, whereas boiling brings water to a higher temperature more quickly. If you are cooking meals that require simmering, such as pasta, you will need to factor in additional fuel to your calculations. The amount of additional fuel will depend on the specific stove you are using and the length of time your meals need to simmer.
Another factor that can impact the fuel required for simmering is wind. Wind can blow away the heat generated by your stove, resulting in longer cook times and increased fuel consumption. If you are camping in windy conditions, it is advisable to bring a windscreen for your stove or additional fuel to compensate for the heat loss. The surrounding air temperature can also affect fuel usage, as colder temperatures can lengthen the time it takes to bring water to a simmer.
To accurately estimate the amount of fuel needed for simmering during your camping trip, it is recommended to test your specific stove and cookware setup. You can do this by weighing your fuel canister before and after boiling a known amount of water. This will give you a baseline for the fuel required for boiling and you can adjust your calculations accordingly for simmering, depending on the additional time and heat required. By considering these factors and planning ahead, you can ensure you have sufficient fuel for your camping trip without carrying unnecessary weight.

Wind: wind can cause higher fuel consumption
When planning a camping trip, it's important to consider how much fuel you'll need, especially if you're camping in windy conditions. Wind can be a significant factor in increasing fuel consumption, and it's essential to be prepared to avoid running out of fuel.
Wind can cause higher fuel consumption for campers in several ways. Firstly, wind can prevent heat from reaching your pot or pan, resulting in longer burn times and increased fuel usage. This is known as the heat-stealing effect of the wind. Experts recommend bringing twice as much fuel if the weather forecast predicts high winds, especially if you don't have a windscreen to block the wind. Additionally, wind can lower the ambient air temperature, making the air denser and increasing aerodynamic drag. This reduced fuel efficiency is particularly noticeable in vehicles, where headwinds and crosswinds can significantly impact fuel economy. For every 10 mph of headwind or crosswind, fuel efficiency decreases by up to 13%.
To combat the impact of wind on your fuel consumption while camping, consider using a windscreen with your stove. This can help block the wind and reduce the amount of heat lost to the environment. It's also essential to prepare your cooking provisions and cookware in advance so that you can start cooking as soon as your stove is ignited, minimizing fuel waste. Covering your pot while cooking can also help, as it reduces evaporation and speeds up boiling, thereby conserving fuel.
Calculating the amount of fuel needed for a camping trip involves considering various factors, including the number of people, the types of meals, and the stove's specifications. As a general rule, plan for boiling one liter of water per person per meal. If your meals require simmering or purifying water, you'll need to bring extra fuel. Additionally, the surrounding air temperature and elevation can affect stove performance and fuel usage, so be sure to take these into account when planning.
To estimate your fuel needs accurately, you can perform a test at home. Boil a liter of water and weigh your fuel canister before and after to determine the fuel cost for boiling one liter of water. Then, consider how many liters you'll need to boil during your trip and adjust for any additional factors, such as wind, elevation, and temperature. It's always better to bring a little extra fuel than to run out during your camping trip.

Elevation: higher elevation affects fuel usage
When planning a camping trip, it is important to consider the impact of elevation on fuel usage. Higher elevation affects fuel usage due to changes in air density and pressure. At higher altitudes, the air density decreases, which can impact the vehicle's aerodynamics and engine performance. This means that vehicles may experience lower fuel efficiency and require more fuel to maintain the same level of performance as at sea level.
The effect of elevation on fuel usage is particularly relevant for car camping trips to mountainous regions or high-altitude areas. The change in air density and pressure at higher elevations can cause a decrease in engine power and fuel economy. As a result, vehicles may consume more fuel to maintain the same speed or performance as they would at lower altitudes.
Additionally, the type of fuel and vehicle configuration can also influence fuel usage at higher elevations. For example, gasoline engines may experience lower fuel consumption at higher altitudes due to reduced throttle friction and wider throttle openings. However, the vehicle's aerodynamic changes due to decreased air density can also play a role in fuel consumption.
To optimize fuel efficiency when camping at higher elevations, it is recommended to consider the following:
- Choose the appropriate fuel type: At higher elevations, it is generally recommended to use a lower octane level of fuel. This is because there is less oxygen per volume of air, and high-octane fuels may not burn efficiently.
- Account for wind conditions: Wind can significantly impact fuel usage, especially when cooking or boiling water. Experts advise bringing extra fuel if high winds are expected, as it may take longer to heat water or cook meals.
- Plan meals accordingly: Consider opting for meals that require boiling water rather than simmering or cooking. Quick-cooking meals, such as freeze-dried meals, instant oatmeal, or tea and coffee, can help reduce fuel consumption.
By considering the impact of elevation and making thoughtful choices about fuel type, meal planning, and wind conditions, campers can optimize their fuel usage and ensure a more enjoyable camping experience, even at higher elevations.

Fuel type: different types of fuel have different burn times
The amount of fuel you will need for a camping trip depends on several factors, including the number of people, the types of meals being cooked, and the environmental conditions. As a general rule, you should estimate boiling one litre of water per person per meal. However, if you need to simmer water for pasta or purifying water, you will need to bring more fuel. Environmental conditions, such as wind, elevation, and temperature, can also impact fuel usage. Wind can prevent heat from reaching your pot or pan, requiring a longer burn time and more fuel. At higher elevations, boiling water takes longer and consumes more fuel. Similarly, cold temperatures can affect fuel performance, especially for pressurised fuel cylinders.
When it comes to fuel type, different types of fuel have different burn times and considerations. Here are some common fuel types used for camping:
- White gas: Also known as naphtha, Shellite, camping fuel, or Coleman Fuel, white gas is a liquid fuel that burns very cleanly. It is widely available in camping and outdoor stores but can be harder to find while travelling abroad or in rural areas. White gas is suitable for liquid fuel stoves and requires priming to initiate the burning process.
- Kerosene: Kerosene is a well-refined liquid fuel that burns well and is easy to find in hardware stores. However, like white gas, it may be harder to come by when travelling internationally. Kerosene can be used in certain camping stoves, sometimes requiring modifications.
- Automotive gas/diesel: Automotive gas is widely available and easier to light than diesel. However, it contains additives such as ethanol to enhance engine performance. Diesel, on the other hand, is thick, challenging to light, and has a strong odour.
- Propane/Isobutane: A blend of propane and isobutane is ideal for most backpackers due to its versatility, minimal weight, broad temperature range performance, and cost-effectiveness. They are commonly used in canisters, providing a consistent and easily controllable flame.
- Alcohol: Alcohol stoves are small, lightweight, and easy to carry, making them a popular choice for campers and backpackers who prefer liquid fuel. Denatured alcohol and pure ethanol are preferred for their clean-burning properties and availability at hardware and liquor stores, respectively. Alcohol stoves can be purchased or made from materials like beer or soda cans.
- Wood: Wood-burning stoves use dry wood sticks or wood pellets as fuel. The availability of dry wood depends on location and weather conditions. Wood-burning stoves may not always be a smart, practical, or legal choice, depending on fire conditions and local regulations.
When choosing a fuel type for camping, it is essential to consider the stove's compatibility, burn time, availability, and ease of use. Additionally, factors such as wind, elevation, and temperature can significantly impact fuel consumption, so planning accordingly is crucial.
