OK, Let's see if I can get this right. this should be very close approximations. Here are a few conversions that you can use. Just read slowly.

Metric to English
100 km/hr = 62 mph
1 liter = .26 gallons

I often just figure that 100km/hr is close to 60 mph (I made the mistake of misreading the speed limit signs in Canada once. I was driving a car with an English speedometer - mph - and forgot the sign was in km/hr. I was close to 80mph which I thought was well under the posted 100 when the Mountie stopped me.

I just figure that 100 km/hr is close enough to 60 mph
and
1 liter is just a little more than a quart of which there are 4 qt to a gallon

Since 60 mph is a common speed I'll use that. This conversion is the other way - English to Metric

60 mph = 96.5 km/hr
1 gallon = 3.8 liters

Now for a common calculation.

60 mpg = 96.5 km/3.8 liters
or
60 mpg = 25.4km/liter

Totally confused? Hope that wasn't too many examples. I have to say that you folks really have the easier system than we do. We are behind the times with a much more cumbersome system to do conversions within.
Just ask someone how many inches in a mile and watch their eyes roll into the back of their head. :lol:
On the other hand to figure how many centimeters in a kilometer all you have to do is move the decimal point.
