Mass & Force Mass & Force

Measurements of mass, force, pressure, and density are some of the most commonly made in the UK. NPL ensures that these measurements can be made traceable to internationally agreed standards. 

Measurements of the mechanical quantities of mass, force, pressure and density are among the most commonly made in everyday life. All of these measurements are derived from the SI unit of mass, the kilogram.

NPL's activity in this area underpins the work of a wide range of industries, from providing traceability for very small weights used in the pharmaceutical industry to testing bridge bearings with loads of thousands of tonnes.

Collaboration

NPL's Measurement Network has an Engineering & Optical Special Interest Group where relevant news and details of events can be found.

Measurement needs

Please tell us about any measurement needs you may have. Some examples of these might be:

  • Issues relating to product inspection
  • Issues relating to process control
  • Training requirements
  • Obtaining specialist calibration or testing support
  • Problem solving on measurement issues
  • Demonstrating or assessing measurement system or product performance

Your input will help us to develop our future work.
