These standards are, essentially, the best available representation of a unit of measurement. Inaccuracy in measurement tools may cause significant errors, impacting any sector that depends on precise measurements.

Take, for instance, the engineering sector where even a minor miscalculation can result in a domino effect leading to inefficient systems or catastrophic failures. Thus, the NMI, with its calibrated tools and standards, is fundamental to ensuring accuracy and safeguarding the robustness of systems.

Around the world, the entities equivalent to NMI also conduct research and development activities to develop national measurement standards. They study science, engineering, and metrology, advancing our knowledge and expertise, and then incorporate them into the measurement standards. By doing this, they constantly enhance the measurement techniques and offer us even better precision.

The pattern approval for instruments used in trade is an important responsibility because it directly affects anyone involved in buying or selling goods. From weighing scales at your local grocery store to fuel dispensers, all these instruments require a pattern approval. If the pattern of measurement is skewed, consumers may be cheated, or traders may inadvertently short-change themselves. This is where the NMI steps in to maintain fairness in trade.

Finally, the NMI is also charged with ensuring legal compliance when it comes to measurements. This means they check whether firms adhere to the laws related to measurements and take necessary actions if there's any violation. This ensures legal measurement compliance and therefore strengthens the trust in the system.

In sum, the NMI plays an integral role in maintaining measurement integrity, ensuring equitable trade, protecting consumers, and fostering research and development in the field of measurements. Its roles and functions are truly indispensable in our society and economy.
