The International System of Units is called "SI"
and is the Metric Measurement used in America.
liter (L)
also spelled litre
is the derived unit for
VOLUME
Use the symbol L
 So you may ask "what's with a capital letter L for liter?
   Is that a capital L for the unit of measure named
after a person like C for Celsius?

No....
You see, when decimal dimensions were described
long before the typewriter we would have to
write the script .

   But as technology came along it became apparent that typewriters were not equipped with so attempts were made to use the lower case "l" (el).
Then it became further confusing to write "1l" (lower case "el")
as the "1" and "l" (el) looked too similar as did the capital "I" (eye).
So the capital L was chosen as the symbol for
the derived base unit liter.
That is the only exception in this so keep going!

		Measure Volume of gasoline or the Volume of most any refreshing beverage.
	Volume is the amount of space in a contained substance like water in a swimming pool measured in liters.
Which has more... 750 mL (milliliters) or 1 L (liter)? • You are Absolutely right!			There are exactly 1000 mL in 1 L (liter)

Liters per 100 kilometers is simply written L/100 km Economy on the road means LESS FUEL IS BETTER! For Instance: A 2009 Pontiac Vibe or a Dodge Avenger SE could get about 6.6 L/100 km (43 mpg) on the highway or 9.9 L/100 km (29 mpg) in the city A quick to determine Fuel Consumption( Video)   Make a note of how many liters it takes to fill up each time... note distance traveled... and find how many liters it takes to travel 100 kilometers (km) DID YOU KNOW? ( Video) that you can divide 1 meter by exactly 10 equal parts (10 cm x 10 cm x 10 cm) then make a cube (1000 cm³) of it to fill with water and you will find that it contains exactly 1 L (1 liter) (1000 mL) of water and is the mass of exactly 1 kg (1 kilogram) (1000 g) ALL SIMPLY RELATED IN 10!
