Mileage Calculator

What is a Mileage Calculator?

A mileage calculator helps you determine your vehicle's fuel efficiency by analyzing the distance traveled and the amount of fuel consumed. It calculates fuel economy in various units including km/L (kilometers per liter), MPG (miles per gallon), and L/100km (liters per 100 kilometers). This helps you monitor your vehicle's performance and identify opportunities to improve fuel efficiency.

How to Use This Calculator

• Step 1: Fill up your tank completely and reset your trip odometer
• Step 2: Drive normally until you need to refuel
• Step 3: Fill up again and note the distance traveled and fuel used
• Step 4: Enter the distance and fuel amount into the calculator
• Step 5: View your fuel efficiency in multiple units

Understanding Fuel Efficiency Units

Different countries use different units to measure fuel efficiency:

• km/L (kilometers per liter): Used in most countries. Higher is better. Typical range: 8-20 km/L
• MPG (miles per gallon): Used in US and UK. Higher is better. Typical range: 20-50 MPG
• L/100km (liters per 100km): Used in Europe. Lower is better. Typical range: 5-12 L/100km

Note: US gallons (3.785 L) are smaller than Imperial gallons (4.546 L), so MPG values differ between US and UK.

Factors Affecting Fuel Efficiency

Several factors can impact your vehicle's fuel efficiency:

• Driving habits: Aggressive acceleration and braking reduce efficiency by up to 33%
• Speed: Most vehicles are most efficient at 50-90 km/h (30-55 mph)
• Vehicle weight: Every 45 kg (100 lbs) reduces efficiency by about 1%
• Tire pressure: Under-inflated tires increase rolling resistance
• Aerodynamics: Roof racks and open windows increase drag
• Engine condition: Regular maintenance keeps the engine efficient
• Weather: Cold weather can reduce efficiency by 10-20%
• AC usage: Air conditioning can reduce efficiency by 5-20%

Environmental Impact

Improving your fuel efficiency not only saves money but also reduces your environmental impact. Every liter of gasoline burned produces approximately 2.3 kg of CO₂. By improving your fuel efficiency by just 10%, you can save hundreds of kilograms of CO₂ emissions per year. This calculator also estimates your CO₂ emissions based on your fuel consumption.
