🧮 How the Petrol Calculator Works
The calculator uses the standard Irish fuel consumption formula:
Fuel Needed (litres) = (Distance ÷ 100) × Fuel Efficiency
Then:
Total Petrol Cost (€) = Fuel Needed × Price Per Litre
Example:
-
Distance: 150 km
-
Efficiency: 6.5 L/100km
-
Price: €1.80 per litre
Fuel needed = (150 ÷ 100) × 6.5 = 9.75 L
Cost = 9.75 × 1.80 = €17.55
The tool performs these calculations instantly and accurately.
