Mosquitoes, common smaller species (about 2.5 milligrams), [53] grain of salt or sand, [54] medicines are typically expressed in milligrams [55] 10 −5 centigram (cg) 1.1 × 10 −5 kg Small granule of quartz (2 mm diameter, 11 milligrams) [56] 2 × 10 −5 kg Adult housefly (Musca domestica, 21.4 milligrams) [57] 10 −4 decigram (dg) 0.27 ...
Conversions between units in the metric system are defined by their prefixes (for example, 1 kilogram = 1000 grams, 1 milligram = 0.001 grams) and are thus not listed in this article. Exceptions are made if the unit is commonly known by another name (for example, 1 micron = 10 −6 metre).
Conversion of units is the conversion of the unit of measurement in which a quantity is expressed, typically through a multiplicative conversion factor that changes the unit without changing the quantity. This is also often loosely taken to include replacement of a quantity with a corresponding quantity that describes the same physical property.
In engineering and science, dimensional analysis is the analysis of the relationships between different physical quantities by identifying their base quantities (such as length, mass, time, and electric current) and units of measurement (such as metres and grams) and tracking these dimensions as calculations or comparisons are performed.
For example, milligram (mg) is used instead of microkilogram (μkg). During mathematical operations, prefixes are treated as multiplicative factors. For example, 5 km is treated as 5000 m, which allows all quantities based on the same unit to be factored together even if they have different prefixes.
{{convert|100|Mm|mm}} → 100 megametres (1.0 × 10 11 mm) The output of {{convert}} can display multiple converted units, if further unit-codes are specified after the second unnamed parameter (without the pipe separator). Typical combination output units are listed below in column 7. {{convert|55|nmi|km mi}} → 55 nautical miles (102 km; 63 mi)
For example, according to the capacitance row of the table, if a capacitor has a capacitance of 1 F in SI, then it has a capacitance of (10 −9 c 2) cm in ESU; but it is incorrect to replace "1 F" with "(10 −9 c 2) cm" within an equation or formula. (This warning is a special aspect of electromagnetism units.
