Fuel Economy and Emissions Calculator

Calculate annual fuel cost, CO₂ emissions, and fuel economy from MPG/L per 100km, annual mileage, and fuel price. Compare gasoline, diesel, E85, and hybrid.

Car miles driven / year

Fuel efficiency (MPG)

🌿 Data Sources: Emission factors from EPA eGRID, IPCC AR6, and EIA. Calculations are estimates for educational and planning purposes. Actual values vary by region, technology, and individual circumstances.

How It Works

Calculate annual fuel cost, CO₂ emissions, and fuel economy from MPG/L per 100km, annual mileage, and fuel price. Compare gasoline, diesel, E85, and hybrid

Each component has a specific meaning:

MPG/L per 100km — The mpg/l per 100km recorded for the patient or scenario being assessed.
Annual mileage — The annual mileage recorded for the patient or scenario being assessed.
Fuel price — The fuel price recorded for the patient or scenario being assessed.

Note: Interpret the fuel economy calculator result against the clinical thresholds and context described above.

How to Use

Enter the MPG/L per 100km, annual mileage, fuel price for the patient or scenario you are assessing. Calculate annual fuel cost, CO₂ emissions, and fuel economy from MPG/L per 100km, annual mileage, and fuel price. Compare gasoline, diesel, E85, and hybrid. Use the fuel economy calculator result to inform your clinical assessment.
