Frequently Asked Questions
Metrology is the broad science of measurement. Calibration is a specific activity within metrology that compares a measuring instrument to a known standard to verify its accuracy.
No. While it includes those, metrology covers all physical quantities: time, temperature, electricity, light, chemical composition, and more.
Metrologists work in national measurement institutes (like NPL in the UK or NIST in the USA), manufacturing industries, aerospace, defence, pharmaceuticals, and any field requiring high-precision measurement.
It provides the globally accepted standards (SI units) and ensures measurements are consistent and comparable worldwide. This builds trust, prevents disputes, and allows components from different countries to fit together.
