Question

What is measurements and its usefulness?

Answer 1

Measurement underpins the welfare of a modern society and touches almost every part of
daily life:
• Ensuring the safety and effectiveness of healthcare diagnostics and treatments
• Measuring the composition, energy value and quantity of gas piped to our homes,
or of fuel in our vehicles
• Ensuring safe operation of aircraft in flight
• Ensuring consistency of international time standards so we can communicate reliably
and navigate accurately throughout the world
• Quantifying emissions of greenhouse gases to understand and mitigate climate change
• Ensuring the security and sustainability of our food supply
• Ensuring fairness between buyers and sellers in markets where goods are sold by
weight or volume
Measurement plays a fundamental part in the innovation process. To develop new products and
processes, companies need to measure quantity, quality and performance. To trade successfully,
companies utilise a regulatory framework, based upon measurement confidence, ensuring access
to global markets that are fair and open and without unnecessary barriers to trade. Supporting
this is an established infrastructure of traceable measurement linked seamlessly to the national
standards maintained on behalf of the UK.
In some industries the need for accurate measurement is critical. For example, companies
manufacturing precision engineering components used in aero engines will be working to tight
specifications and must be able to measure size, material composition and performance to very

Answer 2

Measurement is a cornerstone of trade, science, technology, and quantitative research in many disciplines. Historically, many measurement systems existed for the varied fields of human existence to facilitate comparisons in these fields. Often these were achieved by local agreements between trading partners or collaborators. Since the 18th century, developments progressed towards unifying, widely accepted standards that resulted in the modern International System of Units (SI). This system reduces all physical measurements to a mathematical combination of seven base units.
