** 2011 April 10, Financial Times:As for the large number of official statements that Spain is safe, I think they are merely a metric of the complacency that has characterised the European crisis from the start.
** 2013 August 3, “Boundary problems”, in The Economist‎, volume 408, number 8847:Economics is a messy discipline: too fluid to be a science, too rigorous to be an art. Perhaps it is fitting that economists’ most-used metric, gross domestic product (GDP), is a tangle too. GDP measures the total value of output in an economic territory. Its apparent simplicity explains why it is scrutinised down to tenths of a percentage point every month.

** 2023 October 12, HarryBlank, “Fire in the Hole”, in SCP Foundation‎, archived from the original on 22 May 2024:Ibanez had seen things with worse implications for herself, personally. That was the only metric of horror on which this sight knew remote equal. It was a wall, in a basic sense. It stretched from one side of the tunnel to the other, floor to ceiling, barring further passage. It was pink. It bubbled inside, and it sounded like a hundred simultaneous cases of indigestion which echoed off the rock around it.
* (mathematical analysis) A function which satisfies a particular set of formal conditions, created to generalize the notion of the distance between two points. Formally, a real-valued function $d$ on $M\times M$, where $M$ is a set, is called a metric if (1) $d(x,y)=0$ if and only if $x=y$, (2) $d(x,y)=d(y,x)$ for all pairs $(x,y)$, and (3) $d$ obeys the triangle inequality.
** 2000, Lutz Habermann, Riemannian Metrics of Constant Mass and Moduli Spaces of Conformal Structures‎:As we shall see, these metrics are constructed from a Green function.
* (mathematics) A metric tensor.
* Abbreviation of metric system.
