Except for the early prefixes of kilo-, hecto-, and deca-, the symbols for the prefixes for multiples are uppercase letters, and those for the prefixes for submultiples are lowercase letters. [8] All of the metric prefix symbols are made from upper- and lower-case Latin letters except for the symbol for micro, which is uniquely a Greek letter ...

The prefix kilo, for example, implies a factor of 1000 (10 3), and the prefix milli implies a factor of 1/1000 (10-3). Thus, a kilometre is a thousand metres, and a milligram is one thousandth of a gram.
For example, kilo-denotes a multiple of a thousand and milli-denotes a multiple of a thousandth, so there are one thousand millimetres to the metre and one thousand metres to the kilometre. The prefixes are never combined, so for example a millionth of a metre is a micrometre , not a millimillimetre .
The prefixes of the metric system, such as kilo and milli, represent multiplication by positive or negative powers of ten. In information technology it is common to use binary prefixes, which are based on powers of two. Historically, many prefixes have been used or proposed by various sources, but only a narrow set has been recognised by ...

The factor–label method can convert only unit quantities for which the units are in a linear relationship intersecting at 0 (ratio scale in Stevens's typology). Most conversions fit this paradigm. An example for which it cannot be used is the conversion between the Celsius scale and the Kelvin scale (or the Fahrenheit scale). Between degrees ...
Micro (Greek letter μ, mu, non-italic) is a unit prefix in the metric system denoting a factor of 10 −6 (one millionth). [1] It comes from the Greek word μικρός ( mikrós ), meaning "small".
