Milli, micron and nano These prefixes of units are more common of what we think, especially ' ' milli' '. This text is an attempt to clarify them. In our life, innumerable times, for example, when going to the supermarket/market/bakery to buy cooling, we know that a can of any cooling/beer/juice contains, in volume terms, about 350 milliliters. Also one knows 1000 milliliters (ml) are equivalent the 1 liter. The prefix ' ' mili' ' that it precedes ' ' litros' ' in the word ' ' mililitros' ' power -3 wants to say 10 mathematically high, that is, 0,001. Thus, when some product contains the volume in milliliters, this means that the volume is being express in a unit where each express milliliter 1 liter divided per 1000. That is, a small volume of the liquid in question. Thus, the can of cooling contains, in the total, 350 small volumes equivalents the 1 liter divided per 1000.

Also it can be said that 1 milliliter is equal the 0.001 liter that, as already mentioned, is equivalent to one liter divided per 1000. Of the same one form, when a ruler is used, generally the unit presented in the ruler is of centimeters and still it is possible to notice subdivises of the called centimeters millimeters. One knows that 100 centimeters are equivalent the 1 meter. Then, one millimeter consists of a unit of equal length the 1 meter divided per 1000. One remembers that the prefix ' ' mili' ' the power wants to say 10 high -3. Thus, it can be said that a ruler of a meter possesss about 1000 millimeters, that is, is composed for 1000 subunidades of the meter where each unit valley, in terms of length, 1 meters divided 1000, that is, 0.001 meter.

Also it can be said that 1 millimeter is equal the 0,001. Although much less common, the prefixes ' ' micro' ' whose symbol is ' ' ' ' ' ' nano' ' whose symbol is ' ' n' ' they mean, respectively, 10 high raised -6 and 10 -9.

As it can be noticed, ' ' micro' ' ' ' nano' ' following, for example, meter still assigns lesser units that ' ' mili' ' that we finish of to present. Thus, 1 millimeter is greater that 1 micrometer that, for its turn, is greater that 1 nanometer. A micrometer is equivalent to the subunidade of the meter that, in length terms, wants to say 1 meter divided for 1 million, that is, 1.000.000. Thus, it can be said that 1 meter is equivalent the 1.000.000 micrometers and that the 0.000001 micrometer is equal meter. Thus, it is an extremely miniature unit of length. Using the same displayed reasoning above, 1 nanometer is equivalent the 1 meter divided for 1 billion, that is, 1.000.000.000. In other words, it can be said that 1 meter is equal 1.000.000.000 nanometers or that 1 the 0.000000001 nanometer is equal meter. Thus, also it is an extremely miniature unit of length. In the example, only the meter and the liter had above been used because they are more common units in our daily one. However, milli, micron and nano can be used to subdivide any bigger unit in several of the knowledge as chemistry (MICROmol), physics (MILLIgrama) and much more.
