How to save billions of dollars.

I do however equate 'metrication' with acceptation of the SI, which makes anti-gram arguments against metrication meaningless.

I think most of the arguments have been against using units in stupid ways versus using them in the appropriate settings for their use, not so much anti-gram, specifically. Anything specific to the gram was just making the point with regards to that measure. You could make a similar argument for kilograms, celsius, newtons or whatever other unit you'd like to target.

Regardless whatever point on whatever tangent from the body of this discussion that you're trying to make (I'm honestly not sure exactly what that point is or at least why it would matter at all) it certainly doesn't touch on any of the rest of the discussion.

I find it odd that the kilogram is what they define to be such-and-such (used to be the mass of a reference object, but didn't they fix that?), but it's still a "kilo"-gram. So, really, the "base" unit is the gram, even tho the defined amount is 1000 of them. The CGS systems were equally weird, because they used the "centi" version of a unit as the base. :-P

What I like about the SI units is that they are defined in terms of measurable things - so many oscillations of a cesium atom, so many wavelengths of a particular color of light, etc. Beyond that, I find a lot of them awkward. I admit, a good chunk of that is because it's what I'm used to, but not all. I find the meter to be too long for everyday use (which is why I don't refer to lengths in "yards" either). The cm is too small. A dm would probably be OK, but still on the small side, and nobody uses them anyway. I could probably get used to km instead of mile. I have no intuitive feel for temperatures in C. Liters are an OK size. Electrical units, like the farad, don't need to be very intuitive. So the farad is usually a ridiculously large amount of cap, and we deal in micro-, pico- and fempto- varieties, but it doesn't matter. The picofarad (or "puff") has become an obnoxiously large amount in the semiconductor world.

The "english" units suffer from oddball conversion factors. 12 inches to a foot does make it harder when you have mixed feet and inches. But the "metric" world isn't without their own odd units, despite being factors of 10 to the base unit. The angstrom and the ton come to mind. There are perfectly good ways to express those in terms of meter or gram, but people don't.

Where I do take issue with using traditional units is when you're doing anything especially scientific. There's no reason to use slugs and feet when you're planning an orbit around mars.
