Guide to Imperial Measurents
« on: August 21, 2014, 07:20:16 AM »

As a former draughtsman we all converted to Metric way back in 1971.  Using Metric ever since I am often asked "What's that in English" when I quote a distance.  To be obtuse I usually convert it to the original imperial Barleycorns from which our wonderful Imperial Inch was defined in 1324.

This Number Hub video clip nicely explains how the whole Imperial measurement system works . . .
https://www.youtube.com/watch?v=r7x-RGfd0Yk

At school we had to learn most of these conversions, and how to do long division of Pounds Shillings and Pence.
Few of these units were ever English anyway but ancient foreign imports.

Very good, I like that one.
I must admit to using metric for small work on models, I no longer think 7/32 of an inch, but when it comes to 'how long?' Then it's 61 inches or whatever

Hi Rob I agree, small things metric but I need inches etc. for visualizing longer lengths.

Now that I do not have to sell my time to the best bidder.  I think of all my time as my own and one of my favourite time measurements is the "micro-fortnight"  I think in fortnights as this is how long one pack of pills lasts.

The micro-fortnight is slightly longer than the second and so gives you a little more time to do things.  I used to use "half a tick" but at my age that rather lacks the gravitas of the micro-fortnight.

I, too, use metric for anything below an inch then automatically switch to imperial for all other measurements! And I was born in 1984!!! So well done teachers, I'm born 13 years after decimalisation and I use imperial measurements everyday. Get this though...
I work on an aircraft designed by a consortium of three nations who use metric measurements but the engines are imperial, and strangely two bolts on random parts of the aircraft are imperial too! %%


Someone said to me 'how far is it to Kings Lynn?' So I replied it's about 13 miles, they said 'oh what's that in kilometres?!' To which off the top of my head couldn't answer straight away because like many I suspect we are hard wired to think in imperial for distances and can't visualise a kilometre.


Great link Bob! My dad enjoyed it too! :-))

Love the unit Micro-Fortnight  :-))

With increasing distance it is true we tend to switch to Imperial.  ie: A distance I am prepared to walk is in feet because that's what I use to walk.  However if its further than from the car park to lake side then it is in miles 'cause that is what cars are calibrated in.  Strange, Britain never fully converted.

Today I am sailing my little Springer, which for reference is 2.6 deci-fathoms in length  %%

As a person rooted in Physics, I quite like the

barn.MegaParsec

A barn is approximately equal to the cross sectional area of a Uranium atom. A Mega Parsec is a distance just a bit beyond the Andromeda Galaxy. Multiply them together and you get a volume.

11 of these is a unit of whisky.  :-))

When my sons were at school they laughed at me for using imperial measurements - "poor old chap doesn't he know we've gone metric.....?". Then they left uni and both went into aerospace engineering and lo, they had to learn imperial cos the yanks still use it! Old guys rule!!

I do like millimetres for small measurements, feet are good for measuring rooms, yards are for walking, miles for driving.  The mess of numerators and denominators in small measurements in the imperial system really deserves to be replaced, but fractions are good when cutting a cake.
On a visit to Florida I found the habit of showing the distance to the next turnoff in feet rather disconcerting - my brain thinks in yards.  On the other hand, driving in a metric place like Cyprus was very relaxing, road signs and the speedo were in KM, KMpH, my brains were in miles and MpH.

Hi,

I had a similar experience as RAFLAUNCHES.

I spent my apprenticeship in an old power station where the boilers, being British, were imperial, but the 30MW turbines, being Swiss, were metric.

Every day, when jobs were being issued by the foreman, the mechanics would have to sort out their metric/imperial tools to take out on the job depending whether they were working on the turbine or boiler.

I always remember the confusion one day having taken the wrong feeler gauges to work on the turbine - another job for the "gopfer" (go for this/go for that) to return to the workshop for the correct set.

Another time, at an archaeological dig, the director instructed me to dig a 1 metre 6 inch wide trench!

"How much is your 2 by 1?"
"We haven't got any, it's metric.  We have 50mm by 25mm"
"OK, how much is your 50 by 25?"
"20 pence a foot"


And, shortly after decimal day, I was in need of some 1/8" bits for pop riveting some bits of car back on.  I was informed that they were now metric, so I asked for 3.3mm drill bits.  The guy behind the counter used his public address system of stock checking by looking over his shoulder and shouting "Charlie, have we any three point three meter drills?".  And the right items turned up.

Hi Tiger t, unfortunately long tons.  Did you mean a short ton as 1 Mega grams?
