The kilogram is the only standard unit to include an SI prefix (kilo-) as part of its name. The gram (10 −3 kg) is an SI derived unit of mass. However, the names of all SI mass units are based on gram , rather than on kilogram ; thus 10 3 kg is a megagram (10 6 g), not a * kilokilogram .
The prefix symbols are always prepended to the symbol for the unit without any intervening space or punctuation. [9] This distinguishes a prefixed unit symbol from the product of unit symbols, for which a space or mid-height dot as separator is required. So, for instance, while 'ms' means millisecond, 'm s' or 'm·s' means metre-second.
The second is a link to the article that details that symbol, using its Unicode standard name or common alias. (Holding the mouse pointer on the hyperlink will pop up a summary of the symbol's function.); The third gives symbols listed elsewhere in the table that are similar to it in meaning or appearance, or that may be confused with it;
Small planets, the Moon and dwarf planets in the Solar System have diameters from one to ten million meters. Top row: Mars (left), Mercury (right); bottom row: Moon (left), Pluto (center), and Haumea (right), to scale. The megametre (SI symbol: Mm) is a unit of length in the metric system equal to 1 000 000 meters (10 6 m).
The paper is fed to the drum, and the ink only comes through the master material where there are holes. A pressure roller presses the paper to the drum and transfers the ink to the paper to form the image. The paper then exits the machine into an exit tray. The ink is still wet.
Centi-(symbol c) is a unit prefix in the metric system denoting a factor of one hundredth. Proposed in 1793, [1] and adopted in 1795, the prefix comes from the Latin centum, meaning "hundred" (cf. century, cent, percent, centennial). Since 1960, the prefix is part of the International System of Units (SI).
The official symbol for the SI prefix micro is a Greek lowercase mu (μ). [7] For reasons stemming from its design, Unicode has two different character codes for the letter, with slightly different appearance in some fonts, although most fonts use the same glyph .
Gamma (symbol: γ) is a deprecated non-SI unit of mass equal to 1 μg. [2] A fullwidth version of the "microgram" symbol is encoded by Unicode at code point U+338D ㎍ SQUARE MU G for use in CJK contexts. [3] In other contexts, a sequence of the Greek letter mu (U+03BC) and Latin letter g (U+0067) should be used.
