What was Napoleon's critical influence on the War of 1812?

Napoleon sold America the Louisiana Purchase to help fund an army. This purchase doubled the size of the United States and enabled the expansionist mindset of the Americans. Americans began to push further west which caused conflict with Native Americans and their British allies. Along with the Civil Code, Napoleon brought the metric system to the rest of Europe. The metric system, one of the great creations of enlightened French thought, was put in place by the revolutionaries. It replaced the traditional system of weights and measures, which included erratic numbering and local variations.
