The whole world should switch to the metric system.

Everyone, this debate is my win and I hope you vote me to my win because of the following explanation. Every failure reformation can be justified themselves : 'Only, it is the matter of the time. If the people could bear a little bit more time, this reformation could be successfully finished.' It is only an excuse. We must consider trouble by reformation of people. Current system of time are also illogical that can be compared with the imperial system as I have mentioned before. Why? First, as I have mentioned before, 60 seconds, 60 minutes, 24 hours, 7 days, 28 days, 29 days, 30 days, 31 days, 365 days and 12 months are also so much complexity. Second, current system of calendar also have serious irrational aspects. For example, Gaius Julius Caesar and Augustus arbitrarily manipulate calendar to celebrate with the month of their birth. So the July and October still have 31 days by breaking the rule of calendar. In addition, each year we should change our calendar by sinking money and time. Here, I can point out more weakness related to the current calendar system and I can also show you the new system of calendar that is based on more logical principle than the old system, but I also tell you the reformation is still failure. Why? Because people in the world are so used to using current calendar system and the system of time, so if someone try to change this situation, people have so much trouble in their daily lives. It can be also justified only it is the matter of time, but the costs during the time so expensive so people cannot easily bear the situation. The problem related to the time not only relate to the multiples of 10, but also relate to the similar problems like the imperial system. In a similar logic, USA people are so used to using imperial system in their daily lives. If the standards start to change, I can easily predict much trouble provoke. Related to this problem, you said '95% of the world already uses the metric system and the slight inconvenience of that 5% learning one worldwide system will have great benefits.' But, if we follow this logic, carot and grain(pearl) that are used to the standards of the trading gems should also be changed to the gram because most of other areas use gram, and there are no logical reasons to remain this irrational aspects in this part. In addition, it can also applicated many other parts of the human activity. If Biowza still hope to argue USA should change their system, firstly he should have argued every irrational system should be changed, or secondly he should have proved why the case of USA is so special than others. But he couldn't. Why USA people should only bear the trouble by changing their standards of units? The example of Korea and Austraila are only specific case related to this problem. Of course predictions by Biowza also have possibility. But my country(South Korea) have much more population than Australia. Changing habit of single people is a very hard task you know. In addition, Changing habit of more and more people are more and more hard task. I think USA is much more bigger country than Austraila and South Korea in the aspects of population. The trouble by changing standards is not simple task like the predictions of Biowza. 'Surely if there were to be a clear scientific definition of inches and yards and it proved to be more practical than the metric system, then it would be used.' No, quality does not always guarantee widely used. For example, I can show you VHS win the 'videotape format war' against with Beta. Beta was more advanced system than VHS, but, VHS won because only it was more widely used. And, I already showed you the example of time and calendar. And I add the link. (http://www.idebate.org...) In addition, although imperial system have clear scientific definition and it proved not to be less practical than the metric system, but it is not used because it is the based on English culture. So, it is inadequate to widely used in the world, so metric system was based on the scientific principles to the purpose of widely used in the world. The fact that the meter is based on 1/40000000 of the meridian line is based on the reason. But, as I said before, this fact never prove the imperial system have more irrational than metric system. Summing up. 1. I don't agree that the metric system is a more logical system. Although if I agree, my opposition are not damaged because I already point out the trouble by changing standards. 2. 'I have demonstrated that the switch needs to be made for unity, for safety' But, He did not more consider 'the side effects of changing standards like the cost of changing USA science textbooks, complexity of scientists and students who want to be the scientists who already learned by using old-type science textbooks who already skilled to use two systems of measurements, and so many other things that can set back of the level of USA science.' and many other my proper questions. IN A NUTSHELL, The main purpose of standards of units is improving convenience for people. We should not forget this thing. Changing standards should be considered more carefully. So, everyone. Please vote me to my win.
