Or another classic unit of measurement: football field. "the ship is two football field long." I have never been to American football, so I have no idea about the length of the ship. And they still like their system.
In the grocery store there is a can of coffee and the weight is 22.4 ounces and sells for $ 18.69. There is another can of coffee which contains 18.65 ounces and sells for $15,60. They are absolutely unable to figure out which of the coffee cans is cheaper per pound. And they still like their system. They are confused, but they won't change.

You are either chemist or you look for it in Google. Other than that, people just don't know.

I've worked in imperial and metric and prefer metric. It's calculator friendly, no fractions, intuitive and just easier for me. A mm is smaller than 1/16 and easy to halve by eye.

The hardest part of metric for the new user is developing a visual / mental grasp of the numbers. Some easy ways to start : table hgt. 755mm, internal passage doors 2.1m x 820mm, kitchen bench top hgt. 900mm etc.

I used a metric / imperial tape to start and I soon realized knowing the imperial equivalent was only important to me, everyone else in the shed was in metric. Sort of like constantly trying to convert pesos to dollars, just get a feel for the local prices in pesos.

I agree about Lucas, but that was a problem solved many years ago. I don't thing anything later than the 60s was afflicted with that particular aberration...

As far as beer goes, have you never tried Newcastle Brown Ale???? The very nectar of the Gods! And you obviously never had fish & chips from a good chippie...

The weather? Well, how else do you think we were able to conquer the world?? We needed colonies with better weather for us to vacation in!

You're correct in that I've never had decent fish & chips, at least not that I remember, which may have something to do wit my taste for Directors. Lucas did straighten out. Unfortunately, not while I had my Austin Healey 3000.

The US is in good company. Myanmar and Liberia are the only other two countries in the world that don't us the metric system. Actually according to wikipedia the congress authorized the metric system in 1866. I guess we are just a little slow about changing. :lol: :lol:

I retired back in 93. I was quality control manager of the tool and die div. in the aerospace industry. The metric system is much better. Too change our electric devices it just took the press of a button.

The question of why the U. S. doesn't switch to the metric system has come up here several times. To quote one line from this article, "The benefits of switching are negligible, but the costs are huge." We've all heard the expression, "If it ain't broke, don't fix it."

In the UK we switched years ago, but many of our rulers and tape measures have both measurements on them. Having been brought up with yards, feet and inches and now happy with metres, centimetres and millimetres, I find myself using whichever seems more convenient. It does get complicated though when I find I have a measurement where the length I've measured in metric and the width in feet and inches.

In Canada you can buy 1/2" plywood as 4' x 8' x 13 mm!!! And since 13 mm is more than 1/2" I guess we should consider it a bargain of more for your money (assuming the price did not go up from when it was sold as 1/2"thickness).

An interesting conversion that is easy to remember is converting "mileage" to "consumption", or back the other way from "consumption" to "mileage". Simply divide "FACTOR" by the one unit to get the other.

FACTOR for US gallons is 235.2, and for Imperial gallons it is 282.5 (you can drop the decimals and use 235 or 282 for approximate values).

This works because of the reciprocal (inverted; upside-down) way distance and volume are used in the US/Imperial vs metric approaches to expressing fuel economy.

It is confusing whatever you are trying to calculate.

Sorry if it wasn't clear. I am referring to mpg and L/100 km.

mpg = 235/ (L/100 km); and L/100 km = 235/mpg

Well, that's about two and a half times faster than doing it by the centimeter. And how far to go? East to west? North to south? Both? All around the perimeter? Around the border of each state?

C'mon folks, just do it. You know it's the right thing to do. But do it smarter than we did. We advertise grocery item prices in both units, but the large type face is the price per pound because it's a smaller number. Who are we fooling but ourselves?

Some of these changes are best done in a single fell swoop rather than gradually. Sweden made the switch to drive on the right side of the road on a given day even though folks did not all buy new cars that day. Can you imagine trying to make that sort of change gradually? Yikes!!!
