Tried your extension! A truly worthy extension.

Suggestions and comments after trying it a bit in

- Convert things like ($0.60/Ounce) to $/Gram or $/kg? (2 cents per gram or $21.20 per kilogram in this case!)

Probably the best (and most accessible) book on this subject is The Measure of All Things by Ken Alder. Alder discusses the need for standardised measurements in France, where each municipality had its own weights and measures, resulting in about 250 000 different measures being in use throughout the country. It wasn't only tax officials who wanted to have a national standard for weights and measures, but also merchants, who wanted to trade with other provinces in the country; and scientists who wanted to exchange information with their peers in other countries.

A government committee decided that a ten-millionth of the Earth's circumference would be the standard for the metre. After surveying the meridian from Dunkerque through Paris to Barcelona, a metal bar was produced as a standard.

Since then, the metre has subsequently been defined as a number of wavelengths of a beam of light at a particular frequency, and now is determined as the distance light travels in a defined fraction of a second.

These changes in the definition have not meant that the length of the metre has changed. It just means that the metre is defined with more precision than was possible with previous methods. Also, they ensure that laboratories worldwide can independently make their own standards and use them to calibrate secondary standards, physical metre rulers.

> You are aware, sir, that mileposts are already placed along I-19? Those do not need to be added, just pivoted 90 degrees to be seen from the road. Only the exit numbers need remain.

Easier said than done. We mount signs on U-shaped channel with large flanges. The sign can only be mounted on one face of the post, so the post would have to be uprooted and re-sunk. This Amazon offering will give you an idea of the channel shape if you scroll to top of expanded view:

Edit: MUCH better section views here:

It's still not easy finding basic (and purely) metric measuring tools on Amazon. I'm in the USA. To help others I'll link to what I've found.
Folding ruler
Retracting measuring tape, uses a 32mm system
3.5 meter tape
I'm not having any luck with finding a Celsius-only wall thermometer. Does anyone know of one on Amazon?
Also, US Metric Association has some awesome supplies on their website, but you have to snail mail in an order form.
Somewhat related, here's a really good 24 hour alarm clock. I had no luck finding a 24 hour alarm clock in local stores.

>The channel also refused to let him use the metric system, he said.

Good Eats was so entertaining with Alton demonstrating the science of cooking with puns thrown in. Although, my interest waned whenever ounces, cups, etc. were referenced.
>Brown’s latest cookbook, EveryDayCook: This Time It’s Personal, came out in September.

I previewed the cookbook on Amazon. Apparently the publisher wouldn’t let him use the metric system either. I’m hopeful that he’ll let loose with metric on his new show.

> It is even simpler than this ... in metric there is no ounce, and 30 grams is just 30 grams, and 30 ml is just 30 ml.

Exactly, but in the US there is and many prepackaged products come in increments of one ounce. So, if there is to be a change with minimum or no alteration of package sizes, the 30 for 1 works out the best and as noted by both of us there are more ways to divide into 30 than the 1, 2 & 5 series.

>In Australia if you are ordering a steak dinner at a steakhouse you would probably get to choose either a 250g, 300g, 350g or 400g serving size. No-one uses 480g.

I was just using 480 g as a means to show how it can be divided into a greater number of equal parts. If there was ever going to be a product shift, most likely a pound (454 g) would be downsized to 450 g as the same container can be used. No one would miss the 4 g. There may not even need to be a downsize, just a label change. Even today, 454 g fills are really 460 g to assure no under-sizing.

The same divisibility would apply with 450 g as 480 g. However, when ordering at the deli counter or in a restaurant, 500 g would be the most likely. Very rarely would someone who buys a pound ever divide it into thirds, mostly halves and quarters, so the best way to go would be 500 g divided into 250 g and 125 g. If you still went with 480 g, it would divide this way into 240 g and 120 g and 450 g wold divide into 225 g and 112.5 g.

>As you can see it is commonly sold in a 600ml cardboard package amongst other sizes. The fact that this is relatively close to an imperial pint (which is 568.261 millilitres) is lost to history, and it is sold this way now only because it is a convenient size. If an imperial recipe calls for 1/3 pint of fluid in the metric equivalent recipe this ingredient would probably be listed as 200 ml.

Exactly. 600 mL works out to 20 x 30 mL and is divisible by a whole slew of factors. Industry in Australia could have changed the pint to 570 mL (19 x 30 mL) and had the same effect. In fact, in Australia, Ireland and other countries outside the UK, the legal definition of the old pint is 570 mL, not 568 point blah blah. In the UK pint glassware is really 570 mL and marketed as such:

Just to show a few. The British love to quote the 568 point blah blah millilitres to make the metric number look ridiculous and stress themselves with anger and denial when it is shown to them that their precious pint maybe defined by law as 568 point blah blah millilitres, but in the real world they get their "pint" poured in a nice rounded 570 mL glass. I can't see this ever going to 600 mL as the pubs bend over backwards trying to give less beer and more foam. They would shriek if they were to give 600 mL for the price of 570 mL.

Since Australia metricated decades ago and has already standardised on fixed package sizes there would be no sense in changing them to increments of 30 g or 30 mL. The cost would not be worth it. But for the US, it would be ideal.

If you look on amazon there are a bunch of food scales that are less than 50 USD. There are sales all the time. This is a decent one I have that cost 16 USD. Unless you hate amazon and refuse to do business with them, there is no reason you shouldn't be able to find a decent one under 50 USD.
