miles per gallon
convert:



so,
(kilometers per liter)

change that to units of
;


Easier to look for the volume conversion ratio.
946.353 milliliters is 1 quart, which you might find from some consumer packagings.

Most people learn and continue to remember that 1 mile is 5280 feet.

Most people know that 2.54 centimeters is 1 inch.

You know what to do with these.

Express the given mileage as a fraction:
  33 miles
 ----------
  1 gallon

Then multiply by "unit multipliers" that change units without changing the measurement:
  33 miles     1.61 km     0.264 gallons
 ---------- * --------- * ---------------
  1 gallon     1 mile        1 liter

The units cancel, giving the measurement in kilometers per liter.

Note the unit multipliers are accurate only to a couple of decimal places, so the resulting figure is only approximate.

(33)(1.61)(0.264) = 14.02

ANSWER: 14 km/liter, to the nearest whole number.

Nothing's wrong with the other tutors' answers, but I think nowadays teachers
like for you to multiply by a whole string of unit multipliers.

That's where you always multiply by a fraction with equal numerator and
denominator, but in different units, so that each will cancel away a unit you
want to get rid of and introduce a unit that you want to bring in. 

First you make a "path" for converting each unit:

The "gasoline (or petrol) path" goes from gallons to quarts to liters. 

The "distance path" goes from miles to feet to inches to centimeters to meters
to kilometers. 

You multiply by this long product of unit multipliers (each is actually equal to
1):



Then you go on a unit canceling spree:



and you end up with only some numbers, km on top and L on the bottom:





[Nissan would probably say 14 km/L. Or they might stretch it a bit 
and say 15 km/L. LOL]
