What you'll do
Day-to-day tasks
As a metrologist, you could:
- use handheld and computerised measuring instruments
- check and calibrate measuring tools in line with recognised standards
- troubleshoot problems and fix them
- inspect the dimensions of finished products, tools and machine parts
- record test results for production planning and quality control
- keep up to date with developments in measurement technologies
Working environment
You could work at a manufacturing plant, in a laboratory or visit sites.
Your working environment may be noisy.
You may need to wear safety clothing and use safety equipment.
Career path and progression
You can use your metrology skills to work in many different industries, from environment, energy and aerospace to transport, construction and healthcare.
With experience, you can move into a team management role or specialise in a particular area of measurement and control.
You could also apply for professional registration, with the Institute of Measurement and Control, for Engineering Technician, Incorporated Engineer or Chartered Engineer status.
Registration offers industry recognition of your experience and expertise and can open up further opportunities for career development.

Related subjects
Most relevant
- Mathematics - Metrologists rely on mathematics constantly – from calculating measurement uncertainties and tolerances to applying statistical methods to assess whether products meet required standards. They work with formulas, unit conversions, and data analysis as a core part of every task.
- Physics - Metrologists need a deep understanding of physical quantities like length, mass, temperature, and pressure, as well as how measuring instruments work at a fundamental level. Physics underpins the science of measurement, including concepts like calibration, precision, and the behaviour of materials under different conditions.
- Engineering - Metrologists work closely with engineering teams to ensure that manufactured parts and systems meet exact specifications. They inspect dimensions of machine parts, calibrate tools, and troubleshoot measurement problems – all of which require a solid understanding of engineering principles and manufacturing processes.
- Design and Technology - Metrologists inspect finished products, tools, and machine parts to check they have been made to the correct dimensions. Understanding how products are designed and manufactured – including tolerances, materials, and production methods – helps them identify where problems may have occurred.
Also relevant
- Chemistry - Metrologists working in laboratories or industries like pharmaceuticals and energy may need to measure chemical properties such as concentration, purity, or composition. Understanding chemical principles helps when calibrating instruments used for this type of analysis.
- Computer Science - Metrologists use computerised measuring instruments and may need to write scripts or configure software to automate data collection and analysis. Understanding how digital systems process and store measurement data helps when working with advanced coordinate measuring machines and other programmable equipment.
- Electronics - Metrologists often work with electronic sensors, digital gauges, and computerised measurement systems that rely on electronic circuits. Understanding how these components function helps when calibrating instruments, diagnosing faults, and interpreting readings accurately.
- Business - Metrologists contribute to quality control and production planning, which directly affects a company's efficiency and profitability. Understanding how manufacturing businesses operate helps them communicate the importance of measurement accuracy to managers and production teams.
