Metric System is Redefined

[DirtMechanic]

The Treaty of The Meter 1875 defined the metrics we used until today. Nov 16 bring a vote in Paris to redefine these measures as well as others.

@DirtMechanic I've just read it and couldn't get my head around it, then hubby explained more and in his eyes it's all down to more money again

Thats right. When we make a living we have tools in our hands. The better the tools - the better off we are. When we have fun it is hopefully a brassiere - or a margarita. I am good with either.

Thats right

Hubby says bureauctates messing with people lives...after he read it he went on a rant ….oh my ears

Yes. Basically all forms of metrics are now held by science in the form of mathmatical constants and ratios.

I remember many years ago the state of Massachusetts wanted to round the value of Pi to 3.0
Their reasoning was it would make calculations easier. Never mind that the answer would be wrong. This is what politicians do when they have no real clue what is going on.

@Silentrunning you are somewhat older than I thought.

1897



Lawmakers in Indiana almost pass a bill that erroneously changes the value of pi to a solid 3.2. Cajoled by amateur mathematician Edwin Goodwin, the Indiana General Assembly introduced House Bill 246, which offered up "a new mathematical truth" for free use by the state. The purported truth was Goodwin's attempt to square the circle—a puzzle which requires that a circle and square of the same area be constructed using only a geometrical compass and a straightedge. The bill unanimously passed the House, but the Senate—and hence the state—was spared from embarrassment by C.A. Waldo, a Purdue mathematics professor who happened to be in the State House that day. "Shown the bill and offered an introduction to the genius whose theory it was, Waldo declined, saying he already knew enough crazy people," Tony Long of Wired wrote. Waldo gave the senators a math lesson, and the bill died.

Now you've blinded me with science. Mathematics is not a strong subject of mine unfortunately.

Ah! Metrifiction.

I remember this joke from just after it came in.

A guy goes into a wood yard

"I need 32 ft of three by two."

"Sorry sir, we've gone metric now."

"OK then, give me ten metres."

"Ah! Ten metres you say? Err.. ten metres..... hmmm." Says the assistant looking at his extending tape measure.

"Ten metres? That's about thirty two feet, isn't it?

Back in the early days of working on the ISS there was a major problem with trajectory. After an in-depth study it was found that it was the result of converting inches to meters an vice versa. When we convert a inch to mm it is 25.4mm When most people change to metric they multiply by .03937 for the answer. In reality the correct number is .03937007.

Now I have a headache.

Seriously, when I found out one gram of water is also 1 ml of water, I was happy at the ease of conversion. Now, all I do is measure something of interest and the same volume of water for the specific gravity of that substance against water, and use that simple measurement for grams and vice versa. Ebay sold me a 300 dollar triple beam balance scale for 50 bucks so I am good to .1 grams. The new metric system is accurate to .0000001 I will not be challenging 1 in a billion.

Actually, one in a billion or one billionth is .000000001, but who’s counting?

So from the decimal ;

1)tenths
2)hundredths
3)thousandths
4)ten thousandths
5)hundred thousandths
6)millionths
7)ten millionths

Sound right?

 

[Silentrunning]

You got it! Going to number 4- the big boys would call this tenths of a thousandth. It helps eliminate confusion or misunderstanding.
