The amount of fuel needed depends on several factors, including the type of fuel, the vehicle or system being fuelled, and the desired velocity or distance to be travelled. For example, a 1000-kg rocket needs about 1718.28 kg of fuel to take off from Earth and reach a velocity of 1000 m/s in 30 seconds. On the other hand, it takes 12 billion tonnes of oil to power the planet for a year, while LNG can supply over 20% of the world's energy needs with just 10.4 billion tonnes of gas.

For a boat
The amount of fuel needed for a boat in kilograms depends on several factors. These include the type of fuel, the horsepower, the cruising speed, the duration of the cruise, and the fuel efficiency of the engine.
Firstly, the type of fuel is important. Gasoline engines generally consume about 30% of their horsepower in litres per hour, whereas diesel engines are more fuel-efficient, consuming about 10% of their horsepower in litres per hour. For example, a 100 HP gasoline engine will use about 30 litres of fuel per hour, while a 100 HP diesel engine will use about 10 litres of fuel per hour.
Secondly, the cruising speed and duration of the cruise will affect fuel consumption. For instance, a boat travelling at 15 knots for 5 hours will consume less fuel than a boat travelling at 25 knots for 3 hours, even though the latter trip covers a greater distance.
Additionally, the horsepower of the engine plays a role in fuel consumption. A higher horsepower engine will typically have better fuel economy, as less RPM is needed to maintain a higher speed. For example, a 300-HP diesel engine may burn between 16-17 gallons of fuel per hour, while a 150-horsepower engine will use about 15 gallons per hour.
Other factors that can impact fuel efficiency include the hull shape, engine maintenance, and sea conditions. To keep track of fuel consumption, boat owners can install a fuel monitor or fuel flow gauge, or refer to the engine's fuel flow readouts.
By taking these factors into account and using the appropriate formulas, boat owners can estimate the amount of fuel needed in kilograms for their specific vessel and voyage.

For a car
The amount of fuel needed for a car depends on several factors, including the car's weight, the weight of the fuel, the weight of the passengers, the distance travelled, the speed, the type of engine, the type of fuel, and the fuel economy of the vehicle.
Fuel economy is a measure of how efficiently a vehicle uses fuel, expressed in miles per gallon (MPG) or kilometres per litre (kmpl). The fuel economy of an automobile relates to the distance travelled and the amount of fuel consumed. For example, a vehicle that consumes 100 litres of fuel to travel a distance of 1320 km has a fuel economy of 7.576 L/100 km.
The weight of the fuel carried by a car can also impact fuel consumption. For instance, a car with a base weight of 1200 kg carrying an additional 37.5 kg of fuel would have a total weight of 1237.5 kg. The fuel consumption to carry the additional weight of the fuel is estimated to be 182 litres for 300,000 km.
Additionally, the speed at which a car travels can affect fuel consumption. For example, a 1997 Toyota Celica achieves better fuel efficiency at 60 mph (97 km/h) than at 65 mph (105 km/h), with fuel consumption values of 4.86 L/100 km and 5.41 L/100 km, respectively.
Other factors that influence fuel consumption include wind resistance, tyre drag, engine cooling, air conditioning, and regenerative braking. Overall, the amount of fuel needed for a car can vary significantly depending on a multitude of factors, and it is essential to consider these variables when estimating fuel requirements.

For a fire
The amount of fuel needed to start a fire depends on several factors, including the type of fuel, its moisture content, and the size and composition of the space where the fire will be lit.
For example, fine fuels such as grasses, leaves, pine needles, and thin twigs are quick to ignite and spread fire faster than larger fuels. However, they are also quickly consumed. On the other hand, large pieces of fuel, such as downed logs, may not contribute much to the spread of the fire, but they can burn for extended periods once ignited.
The shape of the fuel also matters. Fine fuels have higher surface area ratios than large fuels, allowing moisture to escape or be absorbed more rapidly. Pine needles and leaves, for instance, have higher surface area ratios than large branches and stems, making them easier to ignite and quicker to burn.
Additionally, the moisture content of the fuel is a critical factor. Dry fuels, such as grass and pine needles, can ignite with a small amount of fuel, while logs and large sticks may require more fuel to overcome their residual moisture.
In a controlled setting, such as a shed, the volume of the space and the proximity of the flame to the fuel source also play a role in determining the amount of fuel needed. For instance, the stoichiometric mixture for a gasoline engine is a ratio of about 14.7 grams of air to 1 gram of fuel. Therefore, knowing the volume of the shed can help determine the amount of gasoline needed for combustion.
Furthermore, the composition of the shed and its contents are factors to consider. A metal shed with ceramic tiles is less likely to catch fire compared to a wooden shed with dry straw.
In summary, the amount of fuel needed for a fire depends on various factors, including fuel type, moisture content, fuel size and shape, space volume, and the flammability of surrounding materials. When determining the amount of fuel required, it is essential to consider these factors to ensure a controlled and safe fire.

For a plane
The amount of fuel needed for a plane to function depends on a variety of factors. These include the type of aircraft, flight distance, weather conditions, and weight of passengers and cargo. For instance, a 747 plane burns 5 gallons of fuel to transport 500 people over 1 mile, whereas the Airbus A380 burns 4,600 gallons of fuel per hour.
The type of fuel used also plays a role in determining fuel efficiency. Jet fuel, typically used in large commercial planes, is usually kerosene-based and is favoured for its high energy content. The freezing point of the fuel is also important, especially for high-altitude flights. Jet A-1, with its lower freezing point, is often preferred for such flights.
Fuel economy is another factor to consider. The typical fuel economy of a plane is 80 passenger-mpg to carry 400 passengers, 8,000 km at 900 km/h, using jet fuel with 12,000 Wh/kg energy density. Increasing velocity degrades fuel economy, with each 100 km/h increase reducing efficiency by around 4 passenger mpg-e. Concorde's top speed of 2,179 km/h hurt its fuel economy by 70%. Conversely, at low velocities, fuel economy suffers because more energy is needed to keep the plane in the air.
Maintenance can also impact fuel consumption. For example, the absence of an engine wash schedule can result in 100 kg more fuel consumed. Additionally, the load factor, or the number of passengers and cargo on board, affects fuel efficiency. A fully loaded plane will be more fuel-efficient than one that is only partially loaded.
Finally, it is worth noting that the shortest flights tend to burn more fuel in taxiing, take-off, and landing than longer flights, where cruising burns the majority of fuel.

For a rocket
The amount of fuel a rocket needs to launch into space is determined by several factors, including the rocket's weight, the thrust produced by its engines, and the orbit it is trying to achieve. For instance, the Falcon 9 rocket from SpaceX typically uses around 902,793 lbs (410,000 kg) of fuel, while the Saturn V rocket, which took the first humans to the moon, required 4,578,000 lbs (2,076,545 kg) of fuel.
A rule of thumb is that 90% of a rocket's weight is fuel. This means that a rocket weighing 1,170 kg would require 1,053 kg of fuel. However, the actual amount of fuel needed can vary depending on the specific requirements and design of the rocket.
The type of fuel used also affects the amount required. Traditional chemical rockets use a combination of liquid fuel and solid rocket boosters, while newer methods like ion thrusters use noble gases like xenon as propellant. Ion thrusters are more efficient but less powerful, and they require a power source like solar panels or nuclear reactors.
The cost of fuel should also be considered. Propellant costs for a rocket like Starship can be estimated at around $500k per launch when purchased in bulk, resulting in a cost of around $5 per kg of payload. The cost of launching 1 kg of payload into orbit with a hypothetical zero-mass rocket is estimated to be around $11, with the cost of fuel being a significant factor.
In conclusion, the amount of fuel a rocket needs varies based on its design, mission, and choice of fuel. While a rough estimate can be made based on the rule of thumb, a more precise calculation requires considering multiple factors and using the rocket equation.
