100 kilometers, 12.8 liters


%28100%2F12.8%29%28kilometers%2Fliter%29

Note that 100%2F12.8=1000%2F128
and also 1000%2F128=%282%5E3%2A5%5E3%29%2F%282%5E3%2A2%5E4%29

125%2F16

7%2613%2F16

To find kilometers per liter, divide kilometers by liters.

Cars in France, and probably other countries, show fuel consumption in "Liters per 100 Kilometers."
I think that's a poor choice.
I think metric units are more rational than using the length of some king's thumb, but that is not a good idea.
Km/liter would make more sense.
