📘 About Fuel Cost Calculation

This calculator helps you estimate the fuel cost for your journey based on your vehicle's fuel efficiency and current fuel prices.

How Fuel Cost Calculation Works

The formula for calculating fuel cost is:

Total Cost = (Distance / Fuel Efficiency) × Fuel Price

Fuel Efficiency Conversions

L/100km to mpg: mpg = 235.214583 / L/100km
mpg to L/100km: L/100km = 235.214583 / mpg
US mpg to UK mpg: UK mpg = US mpg × 1.20095

Factors Affecting Fuel Consumption

Driving habits: Aggressive driving can increase consumption by 15-30%
Vehicle maintenance: Properly inflated tires and regular maintenance improve efficiency
Road conditions: Hilly terrain and rough roads increase consumption
Traffic conditions: Stop-and-go traffic significantly reduces fuel efficiency
Vehicle load: Extra weight decreases fuel economy

Tips to Improve Fuel Efficiency

Maintain steady speeds and avoid rapid acceleration
Keep tires properly inflated
Remove unnecessary weight from your vehicle
Use cruise control on highways
Plan routes to avoid heavy traffic
Keep up with regular vehicle maintenance

❓ Frequently Asked Questions

Fuel efficiency is measured in either liters per 100 kilometers (L/100km) or miles per gallon (mpg), depending on your selection. The calculator automatically converts between these units as needed.

Yes, you can choose between Petrol (Gasoline), Diesel, or LPG. For Petrol and Diesel in USA or UK, live prices are fetched automatically when available.

This calculator provides estimates based on regional average prices. Actual prices depend on your specific location, local taxes, station brand, and current market conditions which can vary significantly.

The calculation is mathematically accurate based on your inputs, but actual fuel consumption can vary due to driving style, vehicle condition, traffic, terrain, and weather conditions.

Yes, simply double the distance for a round trip or use the distance for your entire round trip journey to get the total fuel cost.

US gallons are smaller than Imperial gallons (UK). 1 US gallon = 3.785 liters, while 1 Imperial gallon = 4.546 liters. This calculator uses US gallons for mpg calculations.

Live prices are simulated in this calculator. In a real implementation, they would typically update daily or weekly from reliable fuel price APIs and government sources.
