**Reiny**, Friday, March 7, 2008 at 2:50pmyour 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

= 10.6km/litre

BTW, fuel consumption in the metric system is not expressed as so many km per litre but rather

x litres/100km

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 ?
