How Honda MPG and L/100 km Converter Works
The Honda MPG and L/100 km Converter is a lightweight fuel-economy converter supporting MPG (US), MPG (UK), and L/100 km. Enter a positive value and choose the source unit to convert accurately and see all supported units.
An optional distance-and-fuel-cost mini-calculator estimates fuel use and cost. US and UK gallons differ, so the correct conversion formulas are used.
Calculation and Formula
Conversion formulas
Values are normalized to L/100 km first, then converted to the target unit:
MPG (US) → L/100 km: 235.214583 ÷ MPG (US)
MPG (UK) → L/100 km: 282.480936 ÷ MPG (UK)
L/100 km → MPG (US): 235.214583 ÷ L/100 km
L/100 km → MPG (UK): 282.480936 ÷ L/100 km
Because US and UK gallons differ, MPG (US) and MPG (UK) are not interchangeable.
Distance and fuel cost mini-calculator
Distance km = distance miles × 1.609344
Fuel litres = (distance km × L/100 km) ÷ 100
Fuel cost = fuel litres × price per litre
Frequently Asked Questions
1. Why are MPG (US) and MPG (UK) different?
An imperial (UK) gallon is larger than a US gallon, so the same economy yields a higher MPG (UK) figure.
2. Is L/100 km better than MPG?
L/100 km measures fuel consumed per distance (lower is better); MPG measures distance per fuel (higher is better).
3. Can I calculate trip fuel cost?
Yes. Enter distance and fuel price in the optional mini-calculator.
4. Are results exact?
They are mathematically exact conversions, but real-world economy varies.
5. Can I download the conversion?
Yes. Use the CSV download button or print the page.
6. What units are supported?
MPG (US), MPG (UK), and L/100 km.
7. Is this Honda-specific?
It works for any vehicle but is branded for Honda owners.
8. Can I print it?
