Why has the world not yet agreed upon using one set of units (i.e. meters for distances and kilograms for weight) everywhere?<|im_end|>
<|im_start|>assistant
In large part the world has decided to support a single standard of measurement. The metric system.
Only three countries have not adopted the metric system.
-U.S. 
-Liberia 
-Myanmar

In the case of the U.S. the existing industrial base is too well established to switch standards.
It would be prohibitively expensive to rebuild the industrial infrastructure and retrain workers on a national scale.<|im_end|>

But wouldn't unifying the SI be globally beneficial?<|im_end|>
<|im_start|>assistant
Yes, unifying the SI system would be globally beneficial in several ways:

Improved accuracy and precision: The SI system is based on scientific units that are well defined and standardized, providing improved accuracy and precision in scientific and engineering measurements.

Consistency and interoperability: The use of a single system of units across different countries and industries would reduce the potential for confusion and errors caused by using different units. It would also allow for improved interoperability between different systems and industries.

Improved international cooperation: The adoption of a single system of units would promote international cooperation and collaboration, as well as facilitate communication and understanding between people from different countries and backgrounds.

However, it's important to note that the transition to a single system of units would require significant effort and resources, and may encounter resistance from those who are attached to their existing systems. Additionally, the cost of conversion and retraining may be a significant barrier for some countries and industries. Nevertheless, the benefits of a single system of units would likely outweigh the costs over time, and it would be a positive step towards greater global cooperation and understanding.<|im_end|>
