What's the difference between approximation and metric?

Approximation


Definition:

  • (n.) The act of approximating; a drawing, advancing or being near; approach; also, the result of approximating.
  • (n.) An approach to a correct estimate, calculation, or conception, or to a given quantity, quality, etc.
  • (n.) A continual approach or coming nearer to a result; as, to solve an equation by approximation.
  • (n.) A value that is nearly but not exactly correct.

Metric


Definition:

  • (a.) Relating to measurement; involving, or proceeding by, measurement.
