Fuel consumption calculator

Fuel consumption calculator

Understanding the fuel consumption of your vehicle is a key aspect that not only saves your budget but also impacts the environment. For many motorists, monitoring fuel consumption might seem like a daunting task, but with the fuel consumption calculator, everything becomes simple and accessible. This calculator is designed to calculate fuel consumption (gasoline, gas, or electric charge) per 100 kilometers and also determine the cost of the trip, which allows it to be used in a wide range of situations and types of vehicles.

What is fuel consumption?

Fuel consumption is a measure that shows the amount of fuel required to travel a specific distance. It is one of the main parameters by which the efficiency of a vehicle is assessed. With a wise approach, this information can significantly reduce your expenses and allow you to plan your travel budget.

Fuel consumption in the context of different types of vehicles

Modern automotive engineering offers different types of vehicles, including gasoline, diesel, and electric cars. Each has its unique features in terms of fuel consumption. For example, electric vehicles measure their efficiency in kWh per 100 km, traditional vehicles in liters, and gas-powered vehicles (e.g., using propane or methane) have their own efficiency measurements, often represented in liters or cubic meters.

Using gas, such as propane, can provide significant fuel savings. Propane systems, recognized as environmentally friendly, often offer lower fuel costs, especially over long-term operation.

Formula

The basic formula used to calculate fuel consumption (in liters per 100 km) is:

$\text{Fuel Consumption} = \left( \frac{\text{Fuel Used (L)}}{\text{Distance Covered (km)}} \right) \times 100$

You can also calculate the cost of consumption if the fuel price is known:

$\text{Trip Cost} = \text{Fuel Used (L)} \times \text{Price per Liter}$

Calculation examples

Let’s examine examples for a more comprehensive understanding of the calculator’s functionality:

Example 1: Calculating fuel consumption (gasoline)
Suppose you traveled 500 km and used 50 liters of fuel. Using the formula:

$\text{Consumption} = \left( \frac{50}{500} \right) \times 100 = 10 \text{ liters per 100 km}$

Example 2: Determining the trip cost (gasoline)
If the price per liter of fuel is 1.30 EUR, then for 50 liters used, your cost would be:

$\text{Cost} = 50 \times 1.30 = 65 \text{ EUR}$

Example 3: Calculating fuel consumption (gas, propane)
Suppose you covered 600 km and used 40 liters of propane. The consumption would be:

$\text{Consumption} = \left( \frac{40}{600} \right) \times 100 = 6.67 \text{ liters per 100 km}$

Also, if the price per liter of propane is 0.60 USD:

$\text{Cost} = 40 \times 0.60 = 24 \text{ USD}$

Example 4: Calculating energy consumption (electric vehicle)
Suppose an electric car used 20 kWh over 150 km. The consumption would be:

$\text{Consumption} = \left( \frac{20}{150} \right) \times 100 = 13.33 \text{ kWh per 100 km}$

If the cost per kWh is 0.10 GBP:

$\text{Cost} = 20 \times 0.10 = 2 \text{ GBP}$

Notes

• Unit consistency: Ensure you use the same units for both fuel and distance.
• Driving conditions: Terrain and driving style can significantly affect actual fuel consumption.
• Seasonal effects: In colder months, fuel consumption may increase due to the need for heating.
• For detailed trip planning, you can also use our speed calculator. It helps you calculate the necessary speed for a specific distance or find out how long a trip will take.

Frequently asked questions

How to find fuel consumption if only the distance and used fuel are known?

Use the fuel consumption formula: $\left( \frac{\text{Fuel Used (L)}}{\text{Distance Covered (km)}} \right) \times 100$ to get the result in liters per 100 km.

Why is my car’s fuel consumption higher than specified?

Fuel consumption can vary due to various factors such as driving style, road conditions, vehicle maintenance, and fuel quality.

Can the calculator be used with electric vehicles?

Yes, for electric vehicles, you can use equivalent measures, such as kWh, for efficiency calculation.

What is the fuel consumption for 1,250 km if a car uses 6.5 L over 87 km on the highway?

First, calculate the fuel consumption per 100 km: $\frac{6.5 \text{ L}}{87 \text{ km}} \times 100 = 7.47 \text{ L per 100 km}$.

Then, based on this consumption, calculate the total fuel needed for 1,250 km:

$\frac{1250 \text{ km}}{100} \times 7.47 \text{ L} = 93.375 \text{ L}$

Approximately 93.375 liters of gasoline are needed for 1,250 km.

How often should fuel consumption be checked?

It is advisable to check fuel consumption regularly, especially before long trips, to evaluate the vehicle’s efficiency.
