Doesn't metrology also help us know how developed a country is?
Without measurement, innovation and technological improvements wouldn't be possible. I mean, in order to make something better, you have to measure how good it is currently and how it could be better.
That's why I think metrology can give us hints about how a country is doing in general or how industries in the country is doing. We can measure where they are now, whether they live up to international standards with their products and whether they can compete with other industries globally. It could tell us about a country's economy and even how their health sector is doing.
