"Thus the metric system did not really catch on in the States, unless you count the increasing popularity of the nine-millimeter bullet"

This quote by Dave Barry is a humorous means of mentioning the fact that the metric system has not been commonly embraced in the United States. The metric system is a system of measurement based on the meter, liter, and also gram, and is utilized in most nations all over the world. Nonetheless, in the United States, the conventional system of dimension based on inches, feet, and pounds is still the most typically made use of. Barry is recommending that the only statistics system that has actually ended up being prominent in the United States is the nine-millimeter bullet, which is a type of ammunition utilized in handguns. This is a tongue-in-cheek method of claiming that the statistics system has actually not been extensively approved in the United States, which the only statistics system that has ended up being popular is one that is used for violence.
