your first question makes no sense. You are comparing fuel consumption with speed.
I will assume you meant 25 miles/gallon?
and you are using US gallons.
1 mile = 1.609 km and 1 US gallon = 3.79 litres.
so 25mil/gall = 25*1.609km/3.79litres
BTW, fuel consumption in the metric system is not expressed as so many km per litre but rather
So in our display on a car it might say
fuel consumption: 7.7
so the lower the number the better.
Your second question is a matter of looking up the units, try it
for the third what is 1*1*1 ?
