Metrology is the scientific study of measurement. It's a key factor in achieving accuracy and providing reliable measurements for trade, health, safety, and the environment. Metrology has its roots in the French Revolution, when a length standard taken from a natural source was proposed. Metrology is based on three fundamental quantities: length, mass, and time. All other mechanical quantities, such as area, volume, acceleration, and power, can be derived from these three quantities.  Metrology engineers, or metrologists, specialize in science or engineering-related measurements.  Their...

Metrology is based on three fundamental quantities: length, mass, and time. All other mechanical quantities, such as area, volume, acceleration, and power, can be derived from these three quantities. 

Metrology engineers, or metrologists, specialize in science or engineering-related measurements. 

Their duties may include:
Calibrating instruments
Designing new tools or systems of measurement
Interpreting data
Researching the science of measuring
