About the L/100km Fuel Consumption Calculator

L/100km Fuel Consumption is treated here as a quantitative relation between Fuel Used, Distance Driven and Fuel Price per Liter and Fuel Consumption, Equivalent MPG, Km per Liter and CO₂ per 100 km.

The calculator uses a multi formula configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.

Formula basis:
L/100km = how many liters to travel 100 km. Lower is better (inverse of MPG). Multiply by 2.31 for kg CO₂ (gasoline). Convert to MPG using constant 235.214 (US gallons/miles relationship).

Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.

Formula & How It Works

The calculation applies the following relations exactly as recorded in the metadata:

L/100km = how many liters to travel 100 km. Lower is better (inverse of MPG). Multiply by 2.31 for kg CO₂ (gasoline). Convert to MPG using constant 235.214 (US gallons/miles relationship).

Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.

Worked Examples

Example 1: Toyota Camry equivalent driving: 7.5L used over 95km

Inputs

liters_used: 7.5 km_driven: 95 fuel_price_per_l: 1.6
Fuel Consumption: 7.89 L/100km. Equivalent MPG: 29.8 mpg. Km per Liter: 12.67 km/L. CO₂ per 100 km: 18.24 kg. Fuel Cost for Distance: $12. Efficiency Rating: Good (6-8 L/100km)

With Fuel Used = 7.5, Distance Driven = 95 and Fuel Price per Liter = 1.6 as the stated inputs, the result is Fuel Consumption = 7.89 L/100km, Equivalent MPG = 29.8 mpg and Km per Liter = 12.67 km/L. Each value corresponds to the declared output fields.

Example 2: European diesel SUV: 9.2L used over 110km

Inputs

liters_used: 9.2 km_driven: 110 fuel_price_per_l: 1.75
Fuel Consumption: 8.36 L/100km. Equivalent MPG: 28.1 mpg. Km per Liter: 11.96 km/L. CO₂ per 100 km: 19.32 kg. Fuel Cost for Distance: $16.1. Efficiency Rating: Average (8-10 L/100km)

With Fuel Used = 9.2, Distance Driven = 110 and Fuel Price per Liter = 1.75 as the stated inputs, the result is Fuel Consumption = 8.36 L/100km, Equivalent MPG = 28.1 mpg and Km per Liter = 11.96 km/L. Each value corresponds to the declared output fields.

Example 3: Subcompact city car: 4.5L used over 100km

Inputs

liters_used: 4.5 km_driven: 100 fuel_price_per_l: 1.55
Fuel Consumption: 4.5 L/100km. Equivalent MPG: 52.3 mpg. Km per Liter: 22.22 km/L. CO₂ per 100 km: 10.4 kg. Fuel Cost for Distance: $6.98. Efficiency Rating: Very Good (4-6 L/100km)

With Fuel Used = 4.5, Distance Driven = 100 and Fuel Price per Liter = 1.55 as the stated inputs, the result is Fuel Consumption = 4.5 L/100km, Equivalent MPG = 52.3 mpg and Km per Liter = 22.22 km/L. Each value corresponds to the declared output fields.

Example 4: Performance car track day: 22L used over 80km

Inputs

liters_used: 22 km_driven: 80 fuel_price_per_l: 1.8
Fuel Consumption: 27.5 L/100km. Equivalent MPG: 8.6 mpg. Km per Liter: 3.64 km/L. CO₂ per 100 km: 63.53 kg. Fuel Cost for Distance: $39.6. Efficiency Rating: Poor (>14 L/100km)

With Fuel Used = 22, Distance Driven = 80 and Fuel Price per Liter = 1.8 as the stated inputs, the result is Fuel Consumption = 27.5 L/100km, Equivalent MPG = 8.6 mpg and Km per Liter = 3.64 km/L. Each value corresponds to the declared output fields.
