How Fuel Cost per 100 Kilometers Calculator Works?
This tool works by multiplying liters per 100 kilometers (L/100km) by the price per liter. The result is the fuel cost of 100 km (62.1 miles).
Enter the L/100km rating
Type the consumption figure. The default is 7.5 L/100km, typical for a midsize petrol car.
Enter the price per liter
Type the local fuel price, for example $1.70 per liter.
Read the cost per 100 km
The tool multiplies the 2 values, since L/100km already measures fuel for a 100 km distance.
Scale the result
Multiply by distance in hundreds of km. 800 km equals 8 × the result.
Fuel Cost per 100 Kilometers Calculator Formula
The formula is Cost per 100 km = L/100km × Price per Liter.
Cost per 100 km = L/100km × Price per LiterFormula variables
- L/100km
- Liters burned over 100 kilometers.
- Price per Liter
- Pump price for 1 liter (0.264 US gallons).
Worked example
- Liters per 100km: 7.5 L/100km
- Fuel Price per Liter: $1.70/L
- Multiply 7.5 L/100km by $1.70: 7.5 × $1.70 = $12.75 per 100 km.
- Convert to miles: $12.75 per 100 km equals $20.52 per 100 miles.
Result: $12.75 ($/100 km)
Every 1 L/100km of extra consumption adds the full price of 1 liter to each 100 km. At $1.70 per liter, a car using 9 L/100km costs $2.55 more per 100 km than a car using 7.5 L/100km.
Fuel Cost per 100 Kilometers Calculator Conversion Table
The table shows cost per 100 km for 5 consumption ratings at 3 fuel prices.
Rows: Liters per 100km (L/100km). Columns: Fuel Price per Liter ($/L). Cells: $/100 km.
| L/100km | $1.40/L | $1.70/L | $2.00/L |
|---|---|---|---|
| 4.5 L/100km | $6.30 | $7.65 | $9.00 |
| 6 L/100km | $8.40 | $10.20 | $12.00 |
| 7.5 L/100km | $10.50 | $12.75 | $15.00 |
| 9 L/100km | $12.60 | $15.30 | $18.00 |
| 12 L/100km | $16.80 | $20.40 | $24.00 |
A 12 L/100km 4x4 at $2.00 per liter costs $24.00 per 100 km, close to 3 times the $9.00 a 4.5 L/100km hybrid pays at the same price.
What is Fuel Cost per 100 Kilometers Calculator?
The Fuel Cost per 100 Kilometers Calculator is a metric tool that prices 100 km of driving from consumption and fuel price. The calculator is the metric twin of the cost per 100 miles tool.
European, Canadian, and Australian car makers publish fuel use in L/100km. Multiplying that figure by the local price gives a direct cost, with no conversion to miles or gallons.
The result works in any currency. Enter the price per liter in euros, pounds, or dollars to get cost per 100 km in the same currency.
