Liter Per 100 kilometers

The measurement of fuel efficiency in liters per 100 kilometers (l/100km) provides an arithmetic approach to understanding vehicle consumption. This metric represents the amount of fuel a vehicle uses to travel 100 kilometers, making it easy to compare different vehicles’ efficiency. By using straightforward arithmetic calculations, drivers can determine their vehicle’s fuel consumption in various conditions, such as urban, highway, and combined driving. This unit of measurement is widely used globally for its precision and clarity.

What is Liter per 100 Kilometer?

A liter per 100 kilometers (l/100km) is a measurement unit that quantifies fuel consumption, indicating how many liters of fuel a vehicle requires to travel 100 kilometers. This metric is essential for assessing and comparing fuel efficiency across different vehicles.

    • Example: An electric vehicle does not consume fuel but uses electrical energy instead.


  1. Urban Consumption: Fuel efficiency in city driving conditions with frequent stops and starts.
  2. Highway Consumption: Fuel efficiency in steady highway driving conditions.
  3. Combined Consumption: An average of urban and highway consumption to give a balanced fuel efficiency rating.
  4. Eco Mode Consumption: Fuel efficiency when driving in a vehicle’s eco mode, which optimizes performance for fuel savings.
  5. Sport Mode Consumption: Fuel efficiency when driving in a vehicle’s sport mode, which enhances performance at the cost of fuel efficiency.
  6. Cold Weather Consumption: Fuel efficiency measured in colder conditions, which can affect performance and consumption.
  7. Warm Weather Consumption: Fuel efficiency measured in warmer conditions, typically more efficient than cold weather.
  8. Heavy Load Consumption: Fuel efficiency when the vehicle is carrying a heavy load, usually less efficient.
  9. Light Load Consumption: Fuel efficiency when the vehicle is lightly loaded or empty, generally more efficient.
  10. Idle Consumption: Fuel efficiency measurement while the vehicle is idling, reflecting fuel used without distance traveled.

Liter Per 100 kilometers Formula

Liters per 100 kilometers = (Fuel consumed (liters)​/(Distance traveled (kilometers)) × 100

Km to Liters of Gas

Converting kilometers to liters of gas involves dividing the distance traveled by the vehicle’s fuel efficiency in liters per kilometer (km/l). This calculation provides a summation of fuel consumption, crucial for understanding vehicle efficiency and optimizing fuel costs based on travel distance.

1 liter to km

Converting 1 liter to kilometers involves considering a vehicle’s fuel efficiency, typically measured in kilometers per liter (km/l). This conversion is essential for assessing fuel consumption and its impact on the ecosystem, promoting sustainability and cost-effectiveness in transportation. Understanding this metric helps drivers and policymakers make informed decisions to reduce carbon emissions and preserve environmental health within the ecosystem.

liters per 100km to kmpl

Converting liters per 100 kilometers (L/100km) to kilometers per liter (km/l) involves using the reciprocal of the L/100km value. This conversion is crucial for comparing and understanding fuel efficiency across different vehicles. It’s commonly used in measurement charts to assess and optimize fuel consumption, aiding in vehicle selection and environmental impact mitigation through improved efficiency.

Mpg to l/100km

Converting miles per gallon (mpg) to liters per 100 kilometers (L/100km) involves using a standard formula where 1 mpg equals approximately 2.352 L/100km. This conversion is essential for international fuel efficiency standards and comparisons. It helps in evaluating vehicle efficiency across different measurement systems, aiding consumers and regulators in making informed decisions regarding fuel consumption and environmental impact.

How to Convert Liters per 100 Kilometers

To convert liters per 100 kilometers (L/100km) to standard atmosphere, multiply the L/100km value by 10^-3. This conversion is used in automotive engineering and environmental sciences to assess fuel efficiency and emissions. Understanding this metric aids in evaluating vehicle performance and environmental impact under standard atmospheric conditions, ensuring accurate data interpretation and comparison.
