America should switch to the metric system

As my opponent has brought up the subject of sources again I will have to reply one last time. Lets make this simple. Everything that I used from my source are logical ideas that do not require evidence to support. They do not have to be based on opinions of intelligent individuals. They are simple and easy to understand. Therefore my source is credible. //I provided several examples of confusion that could have been avoided if the US were to switch to the metric system exclusively: science, medical industry, transportation, and commerce.// Could have been avoided yes. But I have dealt with the fact that these problems will likely not happen again. Unless those problems are happening now and often it is not a good reason that we need to switch just because of them. //My opponent also argued that switching to the metric system will fail because it will not "stick". This debate is not about HOW to switch to the metric system but rather, that the U.S. should. I will reserve the how for future debates. I cannot comment whether or not the new system will “stick” because research is needed on my part to propose a plan that will “stick”. This debate is whether or not America should switch, not whether or not it will be successful.// So now we are assuming that it would work. My opponent should have made that more clear earlier on but very well I have no objections. But since we are assuming it would work that brings about another point. Let me make 4 statements. 1. It has been accepted that Americans are lazy. 2. My argument that it would take a long time still holds. 3. If we assume this would work the amount if time and the problems that occur because of it do not matter just as long as in the end it works. 4. Premise one confirms premise two. This proves that it would take a long time for the conversion to the new system to come into effect. I stated earlier that during this time their would be much confusion. Since Americans are lazy we know that their would be both people using the metric system and people using the imperial system. Therefore chaos and confusion would rein. Even more confusion than their is now. The majority of Americans being lazy would not want to change but then the other part would gradually change. Thus for a long time the country would be using two systems. This is even worse than other countries using different systems than ours. My oppoent showed that Canada made the switch but I pointed out that Canda were already partially using the system. Therefore their is no evidence that it would be an easy switch. The metric system may be better, but it is not greatly better than the imperial system currently used. Thus it is not worth it to go through the process of changing systems as in the end it would not be a huge improvement. And I have shown that their would be flaws in the process. //My opponent argues that the imperial system is not terribly difficult but that is also true of the metric system.// Exactly; both systems are not difficult. So like I said it would not be a huge improvement but their would be problems if we were to switch. so therefore the metric system being superior to the imperial system is not substantial evidence that we need to switch. My opponent has not proved that it would be a big improvement and I have shown the flaws of it. The flaws I have shown outweigh the flaws that lie in the imperial system. Thus my opponent has not given substantial proof. Vote con. Thanks to my opponent for the fun debate. And thank you to the voters for taking your time to read through each opponents arguments.
