A milliliter (sometimes written as millilitre) is a

measurement of volume that is equal to one

thousandth of a liter, meaning that it takes one

thousand milliliters to equal one liter. A liter is a

measurement of the amount of space that a liquid

takes up in a container, which is equal to

1.056688 quarts.

To understand this better, picture a gallon of milk.

It takes 4 quarts of milk to make up one gallon of

milk. Since one liter is a little bit more than one

quart, 4 liters of milk is a little bit more than one

gallon of milk.

Now that you know how much is in a liter, you can tell that a milliliter is a very small

amount of liquid. The measurements stated above are based on those used in the United

States. Milliliters are often used in healthcare to measure amounts on liquid medicine.

There are about 5 (4.92) milliliters in one teaspoon and 29.57 milliliters to make one fluid

ounce. Milliliter is often abbreviated as mL or as 1cm3. Milliliter comes from the Greek

word "milli" meaning "one thousand," and the Greek word "litra" meaning "pound." Put the

two words together and you have "one thousand(th) (of a) pound."
