> It's a load-bearing statement. I do understand how someone who lacks grounding in the physical sciences might not realize that. Glad to help. Condescending and wrong, and all in defence of the facially farcical statement that the US uses the metric system. Not that US customary units are defined in terms of metric quantities, which is the moved goalpost you're now trying to defend, but that "the US uses the metric system". Whether or not the US 'uses the metric system' is not contingent on what units US customary units are legally defined in reference to, that's merely trivia.* US customary units do not form part of the metric system, and metric units do not enjoy widespread use in the United States (with minor exceptions). Ergo, the US does not use the metric system. * And relatively recent trivia at that, US units were naturally not first defined in metric units, only later restated as such.
