UK Gas Mileage Formula:
| From: | To: |
The UK gas mileage calculation measures fuel efficiency in miles per gallon (mpg) by converting liters to gallons using the standard conversion factor of 0.21997. This provides an accurate measurement of how many miles a vehicle can travel per gallon of fuel.
The calculator uses the UK mileage formula:
Where:
Explanation: The formula converts liters to UK gallons (1 liter = 0.21997 UK gallons) and then calculates miles per gallon by dividing distance by the converted fuel amount.
Details: Calculating fuel mileage helps vehicle owners monitor fuel efficiency, compare vehicle performance, estimate fuel costs for trips, and identify when a vehicle may need maintenance for optimal fuel economy.
Tips: Enter distance traveled in miles and fuel consumed in liters. Both values must be positive numbers. For accurate results, measure fuel consumption over a significant distance rather than short trips.
Q1: Why use 0.21997 as the conversion factor?
A: This factor converts liters to UK gallons (1 UK gallon = 4.54609 liters, so 1 liter = 1/4.54609 = 0.21997 UK gallons).
Q2: What is considered good fuel mileage?
A: Good mileage varies by vehicle type. Generally, 40-60 mpg is excellent for small cars, 30-40 mpg for medium cars, and 20-30 mpg for larger vehicles or SUVs.
Q3: How can I improve my vehicle's fuel mileage?
A: Regular maintenance, proper tire inflation, smooth driving, reducing excess weight, and avoiding excessive idling can all help improve fuel efficiency.
Q4: Does this calculation work for diesel vehicles?
A: Yes, the same formula applies to both petrol and diesel vehicles when calculating miles per UK gallon.
Q5: How accurate is this calculation?
A: The calculation is mathematically precise. Accuracy depends on the precision of your distance and fuel consumption measurements.
