Every May students throughout the country (and in many other countries) could take Advanced-Placement Exams in many subjects, which could lead to college credits for them.

For example, in Statistics, such an exam has a multiple-choice section and another section of six free-response problems, with the latter available to those interested.

For a change, it was good to see only SI used!

If interested, then here’s a link. Focus on Problems 1 (Page 6) and 3 (Page 8):

asserts the EU did not specify the 700 mL bottle for spirits until 1990, some 10 years after the US specified 750 mL. The prior US fifth, UK sixth (of Imp. gallon) and 750 mL are so close to each other that the same bottle could be used by managing the fill.

If the article is correct, it is all the US’s fault for not correctly guessing that ten years later, the EU would insist on 700 mL. The UK certainly sold Scotch in the US in fifths prior to 1980, even though the same bottle was probably used for “sixths” in the UK.

]]>And looking at the GAO tables reminds me that I learned a new word today, “cambist”.

]]>It seems to me that he asserts 10 Kha to 30 Kha is 10 km² to 30 km². It s/b 100 km² to 300 km²

]]>Your figure of 1000 m² could be expressed as 10 dam² or 10 a, if we brought back the are.

]]>The problem with just using m^2 directly is that using metric prefixes doesn’t increase by factors of 1000, but instead by factors of 1,000,000 and there’s no easy way to just say 1000m^2 using prefixes. That’s because 1km^2 is 1,000m x 1000m, or 1,000,000m^2.

If instead we had a hypothetical unit for area equal to 1m^2, which I’ll call a “mat” for argument’s sake, then I could say “1 kilomat” for 1000m^2, “megamat” for a million, etc. That would be much easier than dealing with hectares.

]]>You should have explained in more details that you were referring to the values on the graph and that 10, 20 & 30 “kha” would become 100 km^2, 200 km^2 and 300 km^2.

Skipping this step in mentioning the reference to the graph made a big difference in comprehending your explanation.

He doesn’t actually state that 10…30 “kha” = 10…30 km^2, just that a kilohectare is 10 km^2. I would suppose he got so hung up on this relationship, he forgot he was dealing with 10…30 and not 1…3.

]]>My suggestions to you is that when the time comes that you need prescription medication, make a point by boycotting all pharmacies that use metric. Also, boycott all over the counter medications dosed in millilitres, milligrams or anything that equals an increment of 5 mL.

In addition refuse to stay in any hospital that works internally in metric especially if the computer they roll around into each of the patients room that has the patient information in metric only. Mass, height, surface area, BMI, body temperature, etc, all in metric.

Avoid all such places no matter what.

]]>Now, take 10 000 000 and reduce the number of zeros by 3 two times. This is leaves you with 10.

Also, 10^4 x 10^3 is 10^7, as the exponents add. 4+3=7. Also, 10^7/10^6 is 10^1 or just 10. 10^3 squared is 10^6.

Use a calculator to verify.
