All the research that is available is in the FPS system. The process of conversion may take decades of repeated research which can result in halting of new inventions to a great extent. And also imagine your clock having 10 hours everyday and 100 minutes every hour. Yes, that's the point.
Which metric system should we use? There are three of them.
Your horrible English scared the metric system away.
