Using Fuel Efficiency Converter with the right inputs
Use Fuel Efficiency Converter locally in your browser. Start by matching your task to the quantities and options shown below. The definitions of the inputs matter as much as the final number or transformed output; retain the original values so that you can repeat or check the result.
Inputs and options explained
- Value: Enter the numeric value for this quantity using the units or scale shown in the label. The form indicates a minimum of 0.
- From: choose Kilometres per litre (km/L), Litres per 100 km (L/100 km), Miles per US gallon (mpg), Miles per UK gallon (mpg).
- To: choose Kilometres per litre (km/L), Litres per 100 km (L/100 km), Miles per US gallon (mpg), Miles per UK gallon (mpg).
Example to try in this tool
Use the following sample values to see how the controls and result fit together. They are an illustration of the operation, not recommended values for your own situation.
- Value: 100
- From: Kilometres per litre (km/L)
- To: Kilometres per litre (km/L)

Converted efficiency
100
This example records the tool’s output for those inputs. Check the method and assumptions against your own task before using a result; reproducing an example is not independent certification of the underlying model.
Interpretation and limitations
Treat entered speeds, prices and durations as assumptions for a particular trip. Real conditions can change with traffic, weather, route choice and breaks. Confirm the units and whether a distance or cost refers to one leg, a return journey or the whole group.
Can this estimate replace a current itinerary or quote?
No. Compare it with current route information, provider prices and your actual schedule. Allow time or budget for items that are outside the inputs shown on this page.
Before you use the output
- Choose the intended action: Convert fuel efficiency. Re-run the operation after changing an input or mode so that you are checking the updated result.
- Read the result label and any accompanying explanation. Keep the input values or source file with the output so that a later comparison uses the same assumptions.
- If a result looks unexpected, check units, separators and selected options first. Try a smaller example you can verify rather than repeatedly changing several settings at once.
Questions or a result that needs checking?
If you find a discrepancy, report a problem with Fuel Efficiency Converter. Include a non-sensitive example, the selected options, the result you expected and the result shown. This makes the issue easier to reproduce. See About & privacy for how the site handles tool inputs.
