Calculate your vehicle's fuel consumption in Australia using this free online calculator. Get accurate fuel efficiency estimates in litres per 100 kilometres (L/100km), which is the standard measurement used in Australia for vehicle fuel economy.
How to Use This Calculator
Using the fuel consumption calculator is simple. Follow these steps:
- Enter the distance traveled in kilometres in the "Distance" field.
- Enter the amount of fuel used in litres in the "Fuel Used" field.
- Click the "Calculate" button to get your fuel consumption in litres per 100 kilometres.
- Review the result and interpretation.
The calculator will display your fuel consumption in L/100km, which is the standard measurement for vehicle fuel economy in Australia. This measurement tells you how many litres of fuel your vehicle consumes to travel 100 kilometres.
Formula Used
Fuel Consumption Formula
The formula used to calculate fuel consumption is:
Fuel Consumption (L/100km) = (Fuel Used ÷ Distance) × 100
Where:
- Fuel Used is the amount of fuel consumed in litres
- Distance is the distance traveled in kilometres
This formula gives you the litres of fuel consumed per 100 kilometres traveled, which is the standard measurement for vehicle fuel economy in Australia.
Worked Example
Let's look at a practical example to understand how the fuel consumption calculator works.
Scenario: You travel 350 kilometres and use 25 litres of fuel.
Using the formula:
Fuel Consumption = (25 ÷ 350) × 100 = 7.14 L/100km
This means your vehicle consumes 7.14 litres of fuel to travel 100 kilometres.
Note
The lower the L/100km value, the more fuel-efficient your vehicle is. For example, a vehicle with a fuel consumption of 5.0 L/100km is more efficient than one with 10.0 L/100km.
Interpreting Results
Understanding your fuel consumption results can help you make informed decisions about your vehicle's efficiency and fuel costs.
Fuel Efficiency Ratings
In Australia, vehicles are rated for fuel efficiency based on their combined city/highway cycle. The ratings are displayed as L/100km, with lower numbers indicating better fuel efficiency.
| Fuel Consumption (L/100km) | Efficiency Rating |
|---|---|
| Below 5.0 | Very High |
| 5.0 - 7.0 | High |
| 7.1 - 9.0 | Medium |
| Above 9.0 | Low |
Cost Savings
You can use your fuel consumption results to estimate fuel costs. For example, if your vehicle consumes 7.0 L/100km and fuel costs $2.00 per litre, your estimated fuel cost per 100km is:
7.0 L × $2.00/L = $14.00 per 100km
This information can help you compare different vehicles or driving habits to save money on fuel.
Frequently Asked Questions
What is the standard unit for measuring fuel consumption in Australia?
The standard unit for measuring fuel consumption in Australia is litres per 100 kilometres (L/100km). This measurement tells you how many litres of fuel your vehicle consumes to travel 100 kilometres.
How do I calculate my vehicle's fuel consumption?
To calculate your vehicle's fuel consumption, divide the amount of fuel used by the distance traveled and then multiply by 100. The formula is: (Fuel Used ÷ Distance) × 100 = Fuel Consumption (L/100km).
What does a low L/100km rating mean?
A low L/100km rating means your vehicle is more fuel-efficient. For example, a vehicle with a fuel consumption of 5.0 L/100km is more efficient than one with 10.0 L/100km.
How can I improve my vehicle's fuel efficiency?
To improve your vehicle's fuel efficiency, consider driving at a steady speed, avoiding rapid acceleration and braking, maintaining proper tire pressure, and keeping your vehicle well-maintained.
Is there a difference between city and highway fuel consumption?
Yes, vehicles typically have different fuel consumption rates in city driving (stop-and-go traffic) and highway driving (steady speed). The combined city/highway cycle is often used to provide an overall fuel efficiency rating.
