No, the problem with test scores is that our teachers wont stop blowing the kids in class long enough to teach them how to read. We have a serious teacher/pedophilia problem. And yes, I'm using the term pedophilia the same as how the libturds use it.

It is commonly used in surveying. Elevations are foot/decimals to the hundredth.

I use this measurement system every day in the aerospace industry. It keeps the same inch, foot, yard system we have, but allows for measuring in very small increments.
I have to hear more about this 'why'......please elaborate.....
what are you measuring, what is the mfg cycling, and with what yardstick????
last time I checked, micrometers were en vogue for pure accuracy at that level.....
aerospace engineering......
I must ask for more technical info before I write anything else....
Well, when they first started using the units of measure, the inch/foot was the measurement system everyone used. Given the close tolerancing necessary, I'm guessing a bit here, they converted inches to hundredths and thousands.
We have stuff that is 6/7 feet in diameter that we machine and measure to +/- .003 and smaller diameters that are machined to +/- .0002. I'm not even sure how you would express and measure those numbers using our standard system.
Btw, a human hair is about .004 in diameter.....
While the metric system seems the logical system to use, when this system began to be used very few Americans knew the metric system so it would be really hard to mentally have a frame of reference.....for me it still is when I see a drawing defined using the metric system....
you simply proved what I was driving at....once the standard UoM is established, converting to decimal format is simple.
it doesn't matter if the tolerance is 0.001/cm or 0.0003937008/in....all that matters is one understands the standard and the tooling/systems in place accounts for either one or both in tandem....
I'm 10 years displaced from that world today.....I still remember the pains I had to go through getting our shop employees to understand why it didn't matter when we converted to decimal formatted drawings....then it really got fun when I was tasked with developing a paperless system.....
there's a part of me that misses those challenges......

Teaching them fractions using the English system hurts their math skills? Sorry Mach, prove it.
XACLY!
understanding the numerator/denominator forces one to think......that's important as the brain is developing.....it absolutely helps develop skills that are required later in life....
anyone can tap keys to find a solution....that's where today's education system is failing in methodology....
once you figure out how to do conversions in your head w/o writing anything down, it really becomes fun.....
once upon, they called me the human calculator.....I'm a tad slower these days as 'use it or lose it' is starting to take effect

It is commonly used in surveying. Elevations are foot/decimals to the hundredth.
in decimal format, it is easily expressed in cm/m/km/etc....
again, the only thing that matters is the standard UoM.....
there's all kinds of reasons why certain standards are what they are.....in the end it simply doesn't matter as long as the tooling is calibrated to the standard.....
For all the whiners, if you can't do simple conversion arithmetics, you don't belong anywhere near a measurement anyway. Using standard weeds out a lot of dippos. Maybe Europe should start using it.

You are correct about the "understanding of the standard".
It's funny, but when I first was exposed to the "inch/decimal" system, it was an easily understandable conversion for me mentally because I could always relate it back to a known - inch or foot.....
It's kind of like a person that learns a second language that is very similar to their first language as opposed to learning a second language that is different enough that the translations always have to convert to first language for understanding.
Who cares? You’re a fool if you can’t use either system. I use metric when converting and dosing meds based on weight in kg. And I use our system when I’m working in my wood shop. It’s not hard to use both.
I think the biggest barrier to our going metric is lack of familiarity. I think if we had a period of dual use, and got familiar with both, then most of us would find metric to be easier and therefore superior.

I would favor a law that everything had to be expressed in both. Kind of like Canada's English/French law. If people started using it and figuring out that metric was easier, I think we would evolve into converting.
Probably the right way to do it. As long as I have worked using and converting between standard and metric I still cant visualize in my head what 304.8 cm is. I know exactly what 10 ft is. Having them shown together would ingrain that visualization eventually.

That's an interesting point. I had to learn to think in the metric system in terms of estimating distance and measurements for a job. It took a little while to do it but once done it was no big deal. 10cm is about 4 inches, a yard is about a meter. A liter is about a quart. Past that you have to measure it with an instrument anyway.

I agree. It's more a cultural thing. If we wanted to we could switch. We just don't want to.
