How can you even attempt to talk about the advantage of normal use, when you don’t even know how to use them?

Metric is a tool. Just because you don’t know how to use the tool, doesn’t mean it’s not advantageous.

Ofc conversions in imperial isn’t necessary, it’s gibberish. No normal person will be able to relate the two.

Are you under the impression that Americans don't know how to use the metric system? We learn to use it in elementary school. We regularly go between the two and relate them to each other.

Your comment is unnecessarily arrogant based on complete ignorance.
