Formula
MPG = km/L × 2.35215; L/100km = 100 / (km/L)
About this calculator
The MPG / km/L Calculator converts fuel consumption between miles per gallon (MPG) and kilometers per liter (km/L), and also calculates liters per 100 kilometers (L/100km). It is useful for drivers comparing vehicles from different countries or needing to interpret consumption data in different units. The tool performs the conversion automatically: simply enter a value in MPG or km/L and the calculator shows the equivalent in the other two units.
The operation is simple and based on direct formulas. To convert km/L to MPG, multiply by 2.35215. To obtain L/100km from km/L, divide 100 by the km/L value. The reverse is also supported: from MPG to km/L, divide by 2.35215; from L/100km to km/L, divide 100 by the L/100km value. The calculator ensures accuracy for everyday use.
When to use? Common situations include: renting a car in another country and comparing consumption with the local standard; evaluating the efficiency of imported vehicles; or converting technical data to report in a specific unit. For example, a car that does 12 km/L is equivalent to approximately 28.2 MPG. The tool is also useful for understanding consumption in L/100km, the standard in many countries.
Cautions: the conversion uses the US gallon (3.785 liters), not the imperial gallon (4.546 liters). Check which standard is used in the original data. Also, remember that actual consumption may vary with driving conditions, maintenance, and load. The calculator provides theoretical values; for accurate measurements, use real refueling data.
Frequently asked questions
What is the difference between US MPG and imperial MPG?
US MPG uses a gallon of 3.785 liters, while imperial uses 4.546 liters. This calculator uses the US gallon, common in the USA.
How do I convert L/100km to km/L?
Divide 100 by the L/100km value. For example, 8 L/100km equals 100/8 = 12.5 km/L.
Can I use this calculator for electric vehicles?
No, it is designed for liquid fuel consumption. For EVs, use units like kWh/100 km.
Is the result accurate for any vehicle?
Yes, the mathematical conversion is exact. However, actual consumption depends on factors like driving style and road conditions.
Which unit is most common in Brazil?
In Brazil, the standard is km/L. L/100km is also used in some contexts, while MPG is rare.
