Reddit reviews Senator Pint Glass with Activator - 570ml 20oz Pint CE marked (Box 24) Ideal for Beer, Water, Soft Drinks

> 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.
