Simple fractions

[LVSteve]

Measuring something is just another way of judging. How intolerant. Maybe the board doesn't like to be described in metric terms.

I used to work in high end metrology, and some of the theory folks hated us, because at the end of the day, measurements proved or disproved their pet theories. Shoot down a great theory, and somebody didn't get to go on an overseas lecture tour or present to a Royal Society. There were days I checked under my car for stray brake fluid after sending back unwelcome results.

Guess its no use bringing up Rods or Chains for measuring land in surveying, LOL

I used to work in a rural county in Maryland that was going suburban, so I had to use and convert these measurements all the time. The old time measurements were copied and recopied down the chain of title until a new survey was done.

Because knowing these measurements was still relevant, I used to teach about them at my company's agents conferences so that our agents would have an understanding in case they ran across the old time measurements.

A neighbor is a community college math instructor, says over half of her classes are remedial level. My niece is program director for respiratory therapy at the same school. Students enroll in science-based degree programs with little or no functional literacy, zero math abilities, no concept of weights or measures.

Kid in my daughters grade wanted to be an anesthesiologist but has ZERO Math Skills. No way I would want that kid administering IV knockout stuff…. Convert patient weight in pounds to Kilograms, cross reference needed dose in micro-liters, and inject.

Too little and patient will feel surgery.
Too much and patient will never feel anything again.

CORRECT MATH IS IMPORTANT

So did my high school analytic geometry/calculus teacher as well as a number of my math, chemistry and physics professors. I found it was easier to learn how to use a slide rule than drive my TI 55, which came with a 9/16" thick instruction manual.

Sounds similar to what happened to me when I was working. A deed plotting program was developed for computers, but I couldn't make it work to save my life. So for 38 years I plotted legal descriptions by hand using a protractor, scale and compass.

I don't know by heart what some of the terms equal, but I DO know what they are. So, I can simply google it to see the conversion factor and all is well.

Nothing wrong with that.

The metric thing never really took off like they'd planned.

My Dad was a carpenter and home builder from 1963 to 1999 or so. And darn good.

He tells me, around 1984, a government study commissioned a house to be built using metric drawings. Nothing lined up, probably because all the trades were using standard measurement tools (and resistant to metric system).

Imagine calling for precuts 233.83875 centimeters!

My wife told me a simple fraction doesn't exist.

In doing land title work I had to understand ancient measurements like links, chains, perches, and roods (not rods) and convert them into modern measurements. It was insinuated that I was George Washington's rod man. I made it a point to teach these things to anybody new in the real estate department at my old firm.

Canoe portages in BWCA and Quetico Park are measured in Rods. A good Boy Scout knows the 320 Rod portage is going to take awhile (and muddy and uphill both ways)

Hard to fathom.

Clever fellow!. I know what you did.

Can anyone convert fractions to decimals, decimals to fractions? (3 place, maybe 4 place decimals) these days? Like these: .125, .312, .5, .437, .687, or heaven forbid .0625?

Have a blessed day,

Yes, sometimes the spelling here is pretty bad.
I almost always proofread before I post, but still miss something sometimes.

I spil perfectly. Its my fat finners tiping thats the problem.

Sometimes spellcheck doesn't work because the misspelled word is actually a real word with different meaning.

My daughter teaches high school in DeLand, Fl and she said you would be amazed at the number of students who cannot tell time with an analog clock.

Around here, a 2 x 4 is actually 1-1/2 x 3-1/2.

When cut in the sawmill it is 2 x 4. The smaller size results after it is planed to be a smooth stud.

I worked in Europe for awhile where it was all metric. They use twobafores in construction, but the actual dimension is not a conversion of 2" or 4" to metric. Just like we use even inch numbers, they use even MM numbers.

As an example a 4' wide sheet of plywood in a metric country is actually 47 inches and change wide.

I forget all the differences, but I guess you get the idea.

Fractions, most kids can't make change for a dollar. There is a vocational school in my county. It use to be kids were college prep or general. The area schools did away with general and forced kids into vocational school. I had a neighbor kid who ended up in Machine Trades. Parents were required to buy basic machinist tools. When kid graduated he ask me if I wanted to buy his tool box. Calipers, mics, ect. This is when I found out the kids were never taught to read instruments. They were using them for no & go gauges. Kids from carpentry classes could read a tape let alone lay out rafters or stair jacks. Reading an old type transit with vernier scale would be like brain surgery to these kids. Not their fault, the so called teachers are not capable of teaching anything they can't read out of book. They are graduating kids that can't read & write. They can't fill out an application without help. It's a crime.

I retired, and my oldest son is a graduate engineer. I'm jus going to leave this measuring stuff to him.

Well a nautical mile is 2025 yards. And a knot of speed in water is 1.15 MPH....
All I ever had to know on a ship.
BTW, Port RED returning....

And the real question is, how many thousands in 1 inch ??

Used to be second nature before I retired, but now I'd need to reference my handy dandy Pipefitters Handbook.

I have drill size, tap-drill sizes, fractions, decimals and who knows what else. I like the full size ones because they are easier on my ole eyes.

What is the smallest threads you ever chased?

The smallest hole I ever drilled is .007 inch. When I could see, I loved to machine small items on the jewelers lathe.

Have a blessed day,

Leon

9 out of 7 people have problems with fraction....I am old and set in my way, but good grief lets got to the metric system.

As it should read:
9 out of 7 people have problems with fraction (s)....I am old and
set in my way (s), but good grief lets got (get on) to the metric system.

Think I'm wrong, test your wife/husband, main squeeze, whatever you call that other person living with you, and after you have been told, then ask her/him/it, to test you some few minutes later.
