Micro- (symbol µ) is a unit prefix in the metric system denoting a factor of 10−6 (one millionth). Confirmed in 1960, the prefix comes from the Greek μικρός (mikrós), meaning "small".
The symbol for the prefix comes from the Greek letter μ (mu). It is the only SI prefix which uses a character not from the Latin alphabet.
Examples:
For historical reasons, there are two different characters in Unicode, which appear slightly different in some fonts, although most fonts use the same glyph. The micro sign (µ) is encoded in the "Latin-1 Supplement" range identical to ISO/IEC 8859-1 (since 1985), at U+00B5
(Unicode 1.0, 1991). The Greek letter (μ) is encoded in the Greek range at U+03BC
. According to The Unicode Consortium, the Greek letter character is preferred, but implementations must recognize the micro sign as well.
Micro or Mikro, from the Greek μικρός (mikrós), means "small". It can be used to indicate a smaller than average scale (microscopic scale), as opposed to prefixes mega and macro, which can be used to indicate a larger than average scale.

In stratigraphy, bedrock is consolidated rock underlying the surface of a terrestrial planet, usually the Earth. Above the bedrock is usually an area of broken and weathered unconsolidated rock in the basal subsoil. The surface of the bedrock beneath soil cover is known as rockhead in engineering geology and identifying this, via excavations, drilling or geophysical methods, is an important task in most civil engineering projects. Superficial deposits (also known as drift) can be extremely thick, such that the bedrock lies hundreds of meters below the surface.
Bedrock may also experience subsurface weathering at its upper boundary, forming saprolite.
A solid geologic map of an area will usually show the distribution of differing bedrock types, i.e., rock that would be exposed at the surface if all soil or other superficial deposits were removed.
Soil scientists use the capital letters O, A, B, C, and E to identify the master soil horizons, and lowercase letters for distinctions of these horizons. Most soils have three major horizons—the surface horizon (A), the subsoil (B), and the substratum (C). Some soils have an organic horizon (O) on the surface, but such a horizon can also be buried. The master horizon, E, is used for subsurface horizons that have a significant loss of minerals (eluviation). Hard bedrock, which is not soil, uses the letter R.
