  metric conversion
Metric conversion is one of the ways that you can upgrade your self, your work group, your company, or your nation to the modern metric system.
Metric conversion is almost always a method to delay upgrading to the metric system directly, quickly, and cheaply.
This is the heart of where metric conversion most often happens in companies when they decide to give the illusion that they are about to 'Go metric' while all the time they have no intention of doing so.

  The Metric System
In 1960, the metric system was officially named the Système International d'Unités (or SI for short) and is now used in nearly every country in the world except the United States.
The simplicity of the metric system stems from the fact that there is only one unit of measurement (or base unit) for each type of quantity measured (length, mass, etc.).
The meter is a unit of length equal to 3.28 feet; the gram is a unit of mass equal to approximately 0.0022 pounds (about the mass of a paper clip); and the liter is a unit of volume equal to 1.05 quarts.

  Metric space - Wikipedia, the free encyclopedia
In mathematics, a metric space is a set where a notion of distance between elements of the set is defined.
Similarly, in 3D, the metrics on the surface of a polyhedron include the ordinary metric, and the distance over the surface; a third metric on the edges of a polyhedron is one where the "paths" are the edges.
An important consequence is that every metric space admits partitions of unity and that every continuous real-valued function defined on a closed subset of a metric space can be extended to a continuous map on the whole space (Tietze extension theorem).

 Metric (mathematics) - Wikipedia, the free encyclopedia
In mathematics a metric or distance function is a function which defines a distance between elements of a set.
A metric induces a topology on a set but not all topologies can be generated by a metric.
Every extended metric can be rescaled to a finite metric (using d'(x, y) = d(x, y) / (1 + d(x, y)) or d''(x, y) = min(1, d(x, y))) and the two concepts of metric space are therefore equivalent as far as notions of topology (such as continuity or convergence) are concerned.

In any metric space M we can define the open balls as the sets of the form A synonym for ball (in geometry or topology, and in any dimension) is disk (or disc Geometry In metric geometry, a ball is a set containing all points within a specified distance of a given point.
If (M,d) is a metric space, S is a subset of M and x is a point of M, we define the distance from x to S as In topology and related branches of mathematics, Tychonoff spaces and completely regular spaces are particularly nice kinds of topological spaces.
A metric space is a 2-tuple (X,d) where X is a set and d is a metric on X. So to decide in what sense two metrics spaces are equivalent we have to discuss continuous functions between them (morphisms preserving the topology of the metric spaces).

Purpose: Students are typically taught large numbers, metric, scientific notation, and engineering notation in different units, in different classes, in completely different years, with little or no effort made to link the ideas.
Engineering Notation - a compromise between the first two - the exponent always corresponds to the metric prefix, that is, the exponent is always a multiple of 3.
For some it might be easier to go from traditional to metric to engineering then to scientific.

 Toward a Metric America: The United States and the Metric System   (Site not responding. Last check: )
The majority of study participants believed that conversion to the metric system was in the best interests of the Nation, particularly in view of the importance of foreign trade and the increasing influence of technology in American life.
This legislation amended the Metric Conversion Act of 1975 and designates the metric system as the "preferred system of weights and measures for United States trade and commerce." The legislation states that the Federal Government has a responsibility to assist industry, especially small business, as it voluntarily converts to the metric system of measurement.
The current effort toward national metrication is based on the conclusion that industrial and commercial productivity, mathematics and science education, and the competitiveness of American products and services in world markets, will be enhanced by completing the change to the metric system of units.

 Hanford Metric Implementation Plan, DOE/RL-94-0070, Rev 1
The DOE Metric Transition Plan states that it is the policy of the DOE to designate and use the metric system of measurement as the preferred system of weights and measures in all of its activities.
The use of the metric system by the DOE and other Federal Agencies is intended to give U.S. firms encouragement and an incentive to convert to the metric system, so that they and the U.S. economy can achieve economic benefits through increased competitiveness in world markets.
This allows a predominantly metric facility to buy nonmetric equipment when a metric-equivalent item is not available (e.g., the procurement of a nonmetric compressor to be installed in a metric system when a metric equivalent is not available).

 Units: The Metric System in the U. S.
Americans could have adopted the metric system, which was then at an uncertain point in its history; or they could have decided to align their measurements with the British Imperial measures established by Parliament in 1824 and thus created a possible alternative to the metric system in international commerce.
However, American consumers generally rejected the use of metric units for highway distances, weather reports, and other common measurements, so little was accomplished except for the encouragement of faster metric conversion in various scientific and technical fields.
Proponents of the metric system in the U.S. often claim that "the United States, Liberia, and Burma (or Myanmar) are the only countries that have not adopted the metric system." This statement is not correct with respect to the U.S., and probably it isn't correct with respect to Liberia and Burma, either.

 Euclidean Metric Matter @ LaunchBase.net (Launch Base)   (Site not responding. Last check: )
In mathematics, the Euclidean distance or Euclidean metric is the "ordinary" distance between the two points that one would measure with a ruler, which can be proven by repeated application of the Pythagorean theorem.
By using this formula as distance, Euclidean space becomes a metric space (even a Hilbert space).
Older literature refers to this metric as Pythagorean metric.

Metric aren't overly adept from a technical standpoint, and their melodies sometimes feel a bit too simplistic, but, in attempting a mix between accessible dance-punk and new wave, they do deliver where it counts: their rhythm section is incredibly tight, and drummer Joules Scott-Key's delightfully funky meter is particularly notable.
