Motor Vehicle Fuel Consumption Calculator

This motor vehicle fuel consumption calculator helps you determine your vehicle's fuel efficiency in miles per gallon (MPG) or liters per 100 kilometers (L/100km). By inputting your distance traveled and fuel purchased, you can calculate your vehicle's fuel consumption and estimate costs.

How to Use This Calculator

Using the motor vehicle fuel consumption calculator is straightforward. Follow these steps:

Enter the distance you traveled in your vehicle.
Enter the amount of fuel you purchased.
Select the appropriate units for distance and fuel.
Click the "Calculate" button to get your results.

The calculator will display your vehicle's fuel consumption in MPG or L/100km, along with an estimated cost per mile or kilometer.

Formula Used

The calculator uses the following formulas to determine fuel consumption:

Miles per Gallon (MPG)

MPG = Distance Traveled (miles) ÷ Fuel Purchased (gallons)

Liters per 100 Kilometers (L/100km)

L/100km = (Fuel Purchased (liters) ÷ Distance Traveled (kilometers)) × 100

Cost per Mile/Kilometer

Cost per Mile = (Fuel Cost ÷ Distance Traveled) × Price per Unit of Fuel

These formulas provide a clear and accurate measure of your vehicle's fuel efficiency.

Worked Example

Let's say you traveled 300 miles and purchased 12 gallons of fuel. Here's how to calculate your fuel consumption:

MPG Calculation: 300 miles ÷ 12 gallons = 25 MPG

Cost Calculation: If fuel costs $3.50 per gallon, your total fuel cost is $42. Your cost per mile is $42 ÷ 300 miles = $0.14 per mile.

This example shows that your vehicle is consuming fuel at a rate of 25 miles per gallon, with an estimated cost of $0.14 per mile.

Interpreting Results

Understanding your vehicle's fuel consumption results can help you make informed decisions about your driving habits and fuel purchases. Here are some key points to consider:

MPG/L/100km: Higher values indicate better fuel efficiency. Compare your results with your vehicle's manufacturer's specifications.
Cost per Mile/Kilometer: This helps you understand how much you're spending on fuel for each mile or kilometer traveled.
Fuel Consumption Trends: Track your results over time to identify patterns and areas for improvement.

By regularly using this calculator, you can monitor your vehicle's fuel efficiency and make adjustments to reduce fuel consumption and costs.

Frequently Asked Questions
