How to save billions of dollars.

That doesn't mean I would use any of them at home.

Sometimes, you do use the metric system 'at home', next to your own customary units. What about this 327 million dollar example?

If you want to interpret 'home' more literally, don't forget your daily dose of tacrolimus.

You keep bringing up quibbles that have already been addressed.

Adressed? Sure. Resolved? No, unless you confirm that the SI base unit for mass is kilogram, and that the international metric system actually abolished the gram as a standard, instead of introducing it. The original gram (as defined by the mass of a cm3 of water) was first proposed in 1795, and the Centimeter-Gram-Second system followed in 1832. Both well before the convention of 1875. This is not a matter of opinion, but simply acceptance of the facts. Once you've done that, read your own post again and see what's left of it.
