Fuel consumption conversions - mpg - km per litre - litres per 100 km

I'm still getting my head around litres per 100 km. It's one thing I still have trouble with after we went Metric. (from Miles per Gallon)
With low mpg numbers (~15) a change of 1 mpg makes a large difference in the litres per 100 k conversion, but as the mpg number rises, the change in the l/100k conversions gets smaller and smaller.
Hard to see in a conversion table or a calculator where you input 1 vale and have it convert to the other.
So I wrote a visual calculator, where you just drag a slider to change all the converted values on a horizontal gauge.
Convert Miles/Gallon to Kilometers/Liter and Liters/100 Kilometers

Drag the KpL slider and watch the difference in the l/100k value as the consumption rises or falls.
Does this make it easier to visualize the conversion?

Is that US gallons, or Imperial gallons?

Unless I have it wrong, and by my calculations, 10/100 km = 28.24 Mpg (Imperial gallons)

Yes, US Gallons. I've labelled it US now.
Will add the option of either US or Imperial.
Thanks for pointing that out.

Thank you again "SIR" for another very helpful calculator....from memory I used to multiply 2.74 times kms per litre = MPG in imperial, as I understood MPG heaps better....Cheers, crowie

I just use a conversion app on my phone...
