Understanding Fuel Consumption
Different Measurement Systems
Fuel consumption and fuel economy are measured differently around the world:
-
Miles per gallon (MPG) - Used primarily in the USA and some parts of the UK
-
Liters per 100 kilometers (L/100km) - Standard in Europe and many countries worldwide
-
Kilometers per liter (km/L) - Common in Japan, Brazil, and other countries
Important Differences
- For MPG and km/L, higher numbers are better (more distance per unit of fuel)
- For L/100km, lower numbers are better (less fuel per unit of distance)
- US gallons (3.785 L) and UK/Imperial gallons (4.546 L) are different sizes
Fuel Economy vs. Fuel Consumption
These terms represent two different approaches to measuring efficiency:
Fuel Economy
Measures how far you can travel per unit of fuel (distance/volume)
- Miles per gallon (MPG)
- Kilometers per liter (km/L)
Fuel Consumption
Measures how much fuel is used for a specific distance (volume/distance)
- Liters per 100 kilometers (L/100km)
Conversion Relationships
The key mathematical relationships for converting between units:
| From | To | Formula |
|---|---|---|
| MPG (US) | L/100km | 235.215 ÷ MPG |
| MPG (UK) | L/100km | 282.48 ÷ MPG |
| L/100km | MPG (US) | 235.215 ÷ L/100km |
| L/100km | MPG (UK) | 282.48 ÷ L/100km |
| km/L | L/100km | 100 ÷ km/L |
| MPG (US) | km/L | MPG × 0.425 |
| MPG (US) | MPG (UK) | MPG × 1.201 |
Real-World Factors Affecting Fuel Efficiency
Many factors can influence your actual fuel consumption:
Vehicle Factors
- Vehicle weight and aerodynamics
- Engine size and type
- Transmission efficiency
- Tire pressure and condition
- Vehicle maintenance
Driving Factors
- Driving speed (optimal is typically 50-80 km/h)
- Acceleration and braking patterns
- Use of air conditioning
- Idling time
- Traffic conditions
How to Convert Fuel Consumption
To convert fuel consumption between different units, follow these steps:
-
1Enter your fuel consumption value in the input field

3Select the unit you want to convert to
1 L/100km = 235.215 / MPG (US)
1 L/100km = 282.481 / MPG (UK)
1 MPG (US) = 235.215 / L/100km
1 MPG (UK) = 282.481 / L/100km
Common Examples
Example 1 7.5 L/100km
7.5 L/100km = 31.4 MPG (US) = 37.7 MPG (UK)
Example 2 30 MPG (US)
30 MPG (US) = 7.8 L/100km = 36 MPG (UK)
Example 3 40 MPG (UK)
40 MPG (UK) = 7.1 L/100km = 33.3 MPG (US)
Example 4 10 L/100km
10 L/100km = 23.5 MPG (US) = 28.2 MPG (UK)
