How to Use Fuel Economy Calculator: L/100km & MPG Converter
3 Easy Steps- Enter Trip DistanceInput kilometers driven on your journey.
- Enter Fuel Consumed & PriceInput total liters of petrol/diesel consumed and cost per liter.
- View Fuel Efficiency & CostInstantly view L/100km, US/UK MPG equivalency, and driving cost per km.
With fluctuating global oil prices and environmental considerations driving automotive decisions, monitoring vehicle fuel efficiency and converting between international fuel economy standards is essential for drivers, fleet managers, and car buyers worldwide. Different countries and automotive manufacturers report fuel consumption using incompatible metrics: North America uses Miles per Gallon (MPG), the United Kingdom uses Imperial MPG, Continental Europe and Asia use Liters per 100 Kilometers (L/100km), and Latin America/India frequently use Kilometers per Liter (km/L).
The EtoolMitra Fuel Economy Calculator & International Converter provides instant bi-directional conversion across all major automotive fuel economy standards: US MPG, UK Imperial MPG, Metric L/100km, and km/L. By inputting distance traveled and fuel consumed, the tool computes your vehicle's real-world efficiency and converts it across all global standards simultaneously.
The tool also features a Trip Fuel Cost Estimator that calculates total fuel volume needed and total financial cost for any planned driving route based on local pump fuel prices. Furthermore, it computes estimated greenhouse gas carbon dioxide (CO2) emissions in grams per kilometer, helping environmentally conscious motorists understand their vehicle's ecological footprint.
Compare vehicle window stickers, diagnose sudden drops in engine fuel efficiency, and optimize your monthly driving expenses with EtoolMitra.

Frequently Asked Questions
Quick answers about Fuel Economy Calculator: L/100km & MPG Converter, formats, and specifications.
What is the difference between US MPG and UK MPG?
A UK (Imperial) gallon is larger than a US gallon (4.546 liters vs 3.785 liters). Therefore, a vehicle measured in UK MPG will display a higher numerical rating than in US MPG for the same fuel efficiency.
How do you convert L/100km to MPG?
To convert L/100km to US MPG, divide 235.215 by the L/100km value. For UK MPG, divide 282.481 by the L/100km value.
Is Fuel Economy Calculator: L/100km & MPG Converter completely free to use?
Yes, this tool is 100% free with no registration, no hidden subscriptions, and no usage limitations.
