  2. Metric - Wikipedia

    en.wikipedia.org/wiki/Metric

    The word metric is often used to mean a descriptive statistic, indicator, or figure of merit used to describe or measure something quantitatively, including: Performance indicator, a measure of an organization's activities and performance; Metrics (networking), the properties of a communication path used by a router to make routing decisions

  3. Metric system - Wikipedia

    en.wikipedia.org/wiki/Metric_system

    The metric system is a decimal-based system of measurement. The current international standard for the metric system is the International System of Units (Système international d'unités or SI), in which all units can be expressed in terms of seven base units: the metre (m), kilogram (kg), second (s), ampere (A), kelvin (K), mole (mol), and ...

  4. System of units of measurement - Wikipedia

    en.wikipedia.org/wiki/System_of_units_of_measurement

    A system of units of measurement, also known as a system of units or system of measurement, is a collection of units of measurement and rules relating them to each other. Systems of measurement have historically been important, regulated and defined for the purposes of science and commerce .

  5. International System of Units - Wikipedia

    en.wikipedia.org/wiki/International_System_of_Units

    The conversion between different SI units for one and the same physical quantity is always through a power of ten. This is why the SI (and metric systems more generally) are called decimal systems of measurement units. [10] The grouping formed by a prefix symbol attached to a unit symbol (e.g. ' km ', ' cm ') constitutes a new inseparable unit ...

  6. Measurement - Wikipedia

    en.wikipedia.org/wiki/Measurement

    The unambiguous meaning of the quantum measurement is an unresolved fundamental problem in quantum mechanics; the most common interpretation is that when a measurement is performed, the wavefunction of the quantum system "collapses" to a single, definite value.

  7. Metric prefix - Wikipedia

    en.wikipedia.org/wiki/Metric_prefix

    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.

  8. List of metric units - Wikipedia

    en.wikipedia.org/wiki/List_of_metric_units

    The first group of metric units are those that are at present defined as units within the International System of Units (SI). In its most restrictive interpretation, this is what may be meant when the term metric unit is used. The unit one (1) is the unit of a quantity of dimension one. It is the neutral element of any system of units. [2]

  9. Measure (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Measure_(mathematics)

    Such a measure is called a probability measure or distribution. See the list of probability distributions for instances. The Dirac measure δ a (cf. Dirac delta function) is given by δ a (S) = χ S (a), where χ S is the indicator function of . The measure of a set is 1 if it contains the point and 0 otherwise.
