micro - It will be anything

Micro(micro, symbol:) µ) shows that it is quantity of 10 times (=0.000 001 times, a one-1000000th) of a unit becoming basic in the one of the prefixes in international unit system (SI) as follows. My black comes from μ ι κ ρ (mikros) of the meaning to "be small" in Greek. When association of British scientific promotion (BA) standardized the electromagnetic unit of the CGS unit system in 1874, it was introduced with mega as the part newly. It was necessary to introduce a new prefix without being enough only with the prefix which there was till then the value to show was very big or to shrink when I made up an electromagnetic unit from a CGS unit system. When SI was established in No. 11 international weights and measures general meeting (CGPM) of 1960, it was approved formally. A sign (Unicode:) U+00B5, HTML: µ) is called "a microsign" and comes from μ of Greek characters. It is often that it is substituted in μ of Greek characters, and there is the thing that μ looks like the same letter depending on a model. µWhen I cannot use も μ, it is substituted in "u". Regardless of a unit, there are some words to name "my black" about the thing that size is small (very much). In this case I can pronounce "micro-@"
