WHAT IS A LITER?
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)
 Compare Fuel Economy in Vehicles Liters per 100 kilometers is simply written L/100 km Make a note of how many liters it takes to fill up each time... note distance traveled... now find how many liters it takes to travel 100 kilometers (km) Economy on the road means LESS FUEL IS BETTER! A quick to determine Fuel Consumption   (Video)    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 cm
ł) 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)

 Share This With Others     May 20, 2019 - REDEFINITION of the KILOGRAM  as a CONSTANT MATHEMATICAL EQUATION For more than a century the world's fundamental unit of mass has been based on a single, cylindrical piece of metal. And authorized copies of it stored in secured chambers around the world including the United States, over the years in infinitesimal ways, are shedding or accumulating atoms here and there, thus throwing off the accuracy of the objects meant to be the world standard for measurements of mass. The 4 cm tall ingot of platinum and iridium, known as the International Prototype Kilogram, offered the world a standardized way of measuring what earlier scientists defined as 1 kilogram being the mass of 1 liter of distilled water (at sea level). But to ensure greater accuracy there is a method of nano-measurement using "Watt Balance" housed at the U.S. National Institute for Standards and Technology (NIST) near Washington, DC, which is a bid to recast the kilogram as a mathematical equation, unerring, immutable and ultimately easy for experts to reproduce. And it is expected to yield groundbreaking calculations. The ultimate purpose of the "Watt Balance" is to help scientists generate a reliable calculation of Planck's Constant. A universal value that quantifies the relationship between energy, light and an object's mass, which in turn will produce a new, more accurate basis for defining the kilogram worldwide. The race to reinvent the unit of measurement was considered important, partly because the kilogram is the only holdout in the metric system still based on a physical object rather than a formula derived from a universal constant. The meter, once pegged to the length of a bar of platinum, was redefined in 1983 by a formula using the speed of light as the distance light travels in a vacuum over 1/299,792,458 of a second. Which means that the length of a meter will never change. The kilogram however is redefined as "JUST A BUNDLE OF ENERGY" While the ampere, kelvin and mole will be tied to the elementary electrical charge, the Boltzmann constant and the Avogadro constant, respectively, the kilogram will now be defined by the Planck Constant. A physical constant that is the quantum of action, which relates the energy in one quantum (photon) of electromagnetic radiation to the frequency of that radiation. A photon's energy is equal to the Planck constant times its frequency. Which is to say, Planck's constant, symbolized h, relates the energy in one quantum (photon) of electromagnetic radiation to the frequency of that radiation. In the International System of units (SI), the constant is equal to approximately 6.626176 x 10-34 joule-seconds. The equation reveals that mass can be understood and even quantified in terms of energy. Planck's equation shows that energy, in turn, can be calculated in terms of the frequency ν of some entity such as a photon (a particle of light), or alternatively, with some mathematical substitutions, a mass- times a multiple of h. The multiple must be a positive integer- such as 1, 2 or 3. The integer aspect is what makes the relationship "quantized" — matter releases energy in discrete chunks, known as “quanta,” which can be imagined as individual packets or bundles of energy. Thus, the ultimate purpose of the "Watt Balance" is to help scientists generate a reliable calculation of Planck's Constant. A universal value that quantifies the relationship between energy, light and an object's mass, which in turn will produce a new, more accurate basis for defining the kilogram worldwide. Just as the meter, once defined as the length of a bar of platinum, was redefined in 1983 by a formula using the speed of light as the distance light travels in a vacuum over 1/299,792,458 of a second. Which means that the length of a meter, like the kilogram now will never change. • HIGGS Boson In July of 2012, scientists at the world's biggest atom smasher in Switzerland claimed the discovery of a new subatomic particle. They called it "consistent" with the long-sought Higgs Boson, popularly known as the "God particle" that helps explain what gives all matter in the universe size and shape. It also adds to the "Big Bang" theory in creation of the universe. The Higgs Boson, which until now has been a theoretical particle, is seen as the key to understanding why matter has mass, which combines with gravity to give an object weight. Very similar to the idea of gravity as Isaac Newton discovered it to be where gravity was there all the time before Newton explained it.
