The word comes from Greek μέτρον (metron), “measure”[1] + “λόγος” (logos), amongst others meaning “speech, oration, discourse, quote, study, calculation, reason”. In Ancient Greek the term μετρολογία (metrologia) meant “theory of ratios”.
Metrology covers three main activities:

  • The definition of internationally accepted units of measurement
  • The realisation of units of measurement
  • The establishment of traceability chains


Metrology is defined by the International Bureau of Weights and Measures (BIPM) as “the science of
measurement, embracing both experimental and theoretical determinations at any level of uncertainty in any field of science and technology.”
