Orders of magnitude (mass) - Wikipedia.

The table below is based on the kilogram (kg), the base unit of mass in the International System of Units ().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 ....

Orders of magnitude (time) - Wikipedia.

An order of magnitude of time is usually a decimal prefix or decimal order-of-magnitude quantity together with a base unit of time, like a microsecond or a million years.In some cases, the order of magnitude may be implied (usually 1), like a "second" or "year". In other cases, the quantity name implies the base unit, like "century".In most cases, the base unit is seconds or years..


Orders of magnitude (data) - Wikipedia.

An order of magnitude is usually a factor of ten. Thus, four orders of magnitude is a factor of 10,000 or 10 4.. This article presents a list of multiples, sorted by orders of magnitude, for units of information measured in bits and bytes.. The byte is a common unit of measurement of information (kilobyte, kibibyte, megabyte, mebibyte, gigabyte, gibibyte, terabyte, tebibyte, etc.)..

Measurement - Wikipedia.

Measurement is the quantification of attributes of an object or event, which can be used to compare with other objects or events. In other words, measurement is a process of determining how large or small a physical quantity is as compared to a basic reference quantity of the same kind. The scope and application of measurement are dependent on the context and discipline..


Parsec - Wikipedia.

The parsec (symbol: pc) is a unit of length used to measure the large distances to astronomical objects outside the Solar System, approximately equal to 3.26 light-years or 206,000 astronomical units (au), i.e. 30.9 trillion kilometres (19.2 trillion miles). Parsec is obtained by the use of parallax and trigonometry, and is defined as the distance at which 1 au subtends an angle of one ....


Electrical resistivity and conductivity - Wikipedia.

Electrical resistivity (also called specific electrical resistance or volume resistivity) is a fundamental property of a material that measures how strongly it resists electric current.A low resistivity indicates a material that readily allows electric current. Resistivity is commonly represented by the Greek letter ? ().The SI unit of electrical resistivity is the ohm-meter (??m)..

Input impedance - Wikipedia.

The input impedance of an electrical network is the measure of the opposition to current (), both static and dynamic (), into the load network that is external to the electrical source. The input admittance (the reciprocal of impedance) is a measure of the load's propensity to draw current. The source network is the portion of the network that transmits power, and the load network is ....


Inductance - Wikipedia.

Inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it. The flow of electric current creates a magnetic field around the conductor. The field strength depends on the magnitude of the current, and follows any changes in current..


Watch - Wikipedia.

A movement of a watch is the mechanism that measures the passage of time and displays the current time (and possibly other information including date, month, and day). Movements may be entirely mechanical, entirely electronic (potentially with no moving parts), or they might be a blend of both. Most watches intended mainly for timekeeping today have electronic movements, with ....

where is the mole fraction of species i.. Fick's second law. Fick's second law predicts how diffusion causes the concentration to change with respect to time. It is a partial differential equation which in one dimension reads: = where ? is the concentration in dimensions of [(amount of substance) length -3], example mol/m 3; ? = ?(x,t) is a function that depends on location x ....


Technological singularity - Wikipedia.

The technological singularity--or simply the singularity --is a hypothetical point in time at which technological growth will become radically faster and uncontrollable, resulting in unforeseeable changes to human civilization. According to the most popular version of the singularity hypothesis, I.J. Good's intelligence explosion model, an upgradable intelligent agent will eventually enter a ....


Metric prefix - Wikipedia.

A metric prefix is a unit prefix that precedes a basic unit of measure to indicate a multiple or submultiple of the unit. All metric prefixes used today are decadic.Each prefix has a unique symbol that is prepended to any unit symbol. The prefix kilo-, for example, may be added to gram to indicate multiplication by one thousand: one kilogram is equal to one thousand grams..


Science fiction - Wikipedia.

Forrest J Ackerman has been credited with first using the term "sci-fi" (analogous to the then-trendy "hi-fi") in about 1954; the first known use in print was a description of Donovan's Brain by movie critic Jesse Zunser in January 1954. As science fiction entered popular culture, writers and fans active in the field came to associate the term with low-budget, low-tech "B-movies," ....
