Convert fuel economy between MPG, L/100km, km/L, miles per liter, and related driving efficiency units. Estimate fuel used and trip fuel cost from distance, fuel economy, and fuel price.
MPG US to L/100km:
L/100km = 235.214583 ÷ MPG US
L/100km to MPG US:
MPG US = 235.214583 ÷ L/100km
MPG US to km/L:
km/L = MPG US × 0.425144
km/L to MPG US:
MPG US = km/L ÷ 0.425144
Fuel economy conversions are useful for comparing cars, trucks, SUVs, motorcycles, hybrid vehicles, international vehicle specs, road trips, fuel cost planning, MPG ratings, and L/100km ratings.
Use this converter when comparing fuel economy numbers from different countries or when estimating fuel used for a trip.
Your result shows the entered fuel economy converted into the selected unit. The converter also displays MPG US, MPG UK, L/100km, km/L, miles per liter, estimated fuel used, and estimated trip fuel cost.
Real fuel economy can vary because of driving speed, traffic, weather, tire pressure, vehicle load, engine condition, terrain, fuel type, towing, and driving habits.
For MPG US, divide 235.214583 by the MPG value. For example, 25 MPG US is about 9.41 L/100km.
For MPG US, divide 235.214583 by the L/100km value. For example, 8 L/100km is about 29.4 MPG US.
Yes. Higher MPG means the vehicle travels farther on each gallon of fuel.
Yes. Lower L/100km means the vehicle uses less fuel to travel 100 kilometers.
MPG UK uses the imperial gallon, which is larger than the US gallon, so MPG UK values are usually higher for the same vehicle efficiency.
