back in the day i remember working on the tail fin of a 747 and finding out that my 3/8 spanner was a size too big
so what's 1 size down?
2/8 is a 1/4, that was too small
but 3/8 is also 6/16 so maybe it was 5/16
but that was small too
so it was back down in the cherry picker for that very rare aircraft spanner
1 size up from the 5/16, which is also 10/32
11/32!
when you are tired it just much easier to think 5,6,7,8mm... -

Well you were certainly over my head but it was interesting reading. "The kids learn it in 10 minutes and never forget" however I can speak as an authority "balderdash "( to use an archaic English term) You obviously are not a high school math teacher.
I did tell my students once that we were going on metric time 10 sec to a min, 10 min to 1 hour, 10 hours to a day, 10 weeks to a month, 10 months to a year. Thy bought it. Parents called and wanted to know when the switch.
With an ox cart I wouldn't need beach wheels so I guess we haven't progressed.

All I know is that my Nacra 5.2 was faster than my buddy's Hobie 16 so there must be something better about the metric system. I am stuck with the old system but I have to admit that tools are a lot easier to figure out when you are working in metric units.
What I think is funny is that I have pretty much forgotten all the conversion formulas. I know that 10 Km is equal to 6.2 miles and do the math that way. I know that 5.0 meters is about 16 feet and some change. That's about as far as my math goes for converting.

we used to have a "fathom" club
if you could stand in a fathom of water and the top of your head was dry, you were a "fathom"
if you couldn't do that, you were a "blot" -

The metric system is easier in almost all respects, and I no longer hang my patriotism on the English system.
The Brits gave us "hands" and "feet" and then bailed on the entire thing for the millimeter.
The US officially adopted the metric system as legal measurement in 1866, the year after the Civil War ended.
We're just a little slow on the uptake.

looking around the house i noticed pretty much everything has standard and metric units on them, it's here to stay for sure...they use the metric where it really counts like the hospitals(they don't measure drugs by the teaspoon anymore)...now you can measure soccer players by centimeters and kilos but in america we like to hear our football and basketball players in good old fashion terms...take damon, for example, he's like 6'29" or so...it sound cooler when you hear your team has 2 seven footers!!! hell, you need both sets of sockets to do a job because one or more of each is missing and the others will work anyway. the good thing about standard measurements in construction is it keeps your fraction skills sharp for important things like estimating how much beer is left in the keg...1/3?, 2/3?,...and so on. hope this clears things up! oh, and music is on the fraction scale too...very important...

In forestry and surveying we measure in chains. There are 80 chains in a mile. Also, a chain is 66 feet.
Stew on that a while.

Isn't a standard road allowance 1 chain? We used to timber cruise in board feet, & though you still buy hardwood that way, I think our guys now measure standing timber in cubic meters.
Way back when I was doing engineering work for water projects, Canada converted its surveys to metric. That was about a 4 year delay after implementation of the system. From that date all surveys/blueprints had to be submitted in metric. The long stick that the field guys ran around with taking "shots" was called a rod, hence they were rodmen. I think it was 16 1/2', hence 4 of them equaled a chain. When conducting precision surveys, usually for the design of spillways in dams, the "chaining" had to be accurate. We hooked a scale to one end of the "chain",(which was not actually a chain, but a steel tape resembling a sewer snake. It was then stretched to 40lbs tension, & the temperature taken to account for thermal expansion. Measurements were taken from a tack driven into a 2x2 hub. The tack had a pinhole in the center, from which the measurement was initiated.
No one had a "metric rod" for shooting stadia at the time so myself & two colleagues were tasked with designing one. After several days the eureka moment struck, we didn't have to invent anything, just have the stadia side of the rod painted in 1/10 of a meter increments, alternating black/red for visibility. The transit X hairs & declination angles would work exactly the same as before, only the results would be meters instead of yards. The front side would have a centimeter tape for precision shots.
In practice it turned out to be much better than the old system. Because everything was based on multiples of 10, you could convert the shot into meters in your head, as you recorded it. The old way you had to count inches & feet, then run it through a formula.
That was in the old days, instrument men today just click a button on their Theodolites, & the numbers get crunched. Gone are the days of yelling out readings to note takers, & having them plot on a plane table as the rodmen walked the grids. Even though I did that work for 4 years, I still have to think about an acre, it's 43 thousand some odd square feet, so how many gallons or cubic yards of water do you store with a 1500 acre feet system?
The metric system is just so much easier, even 30 odd years later I can crunch those numbers in my head. Unless you have suffered a stroke it is hard to forget how to manipulate 10's, 100's or 1000's. I still wonder what the guy was smoking when he came up with water freezing at 32F & boiling at 212F. Tell a kid 0 & 100, they never forget it.
Probably one of the most common tasks is premix gas/oil for two strokes. If you need 50:1 how many ounces do you add to a 5 gal can? What about the odd engine that wants 32:1? With metric you do the math in your head, to borrow a line from Philip, so easy a caveman...

You are lucky. We bring those 10 & 20 litre kegs of good German beer back from Munich or Frankfurt...they always seem to be empty! Accentuating the positive, they are much more convenient on a Cat, the only way to cool the 60L models is in a cut off 50 gal drum.
Those are hard to find here, & you could buy a 2nd Cat with what they cost, compared to jugs. One must also remember that there are at least two sizes of gallons, the Imperial being 20% larger than the US gal.
I think the only place that stocks them is the Stihl chainsaw dealer. I still have a large 2 stroke in the fleet, we buy oil in 5 litre jugs.
Jerry cans only hold 23 litres, or 30 for the large ones, makes for awkward numbers in gallons, & awkward mixing. Small tools such as weed eaters & chainsaws don't use much fuel. In order to prevent problems resulting from stale fuel we generally only mix 4 or 5 litres (1 of your gallons, 1 of our gallons respectively) for a season, using something like Shell V-Power, as it contains no ethanol. If I ever forgot that 100ml in 5000ml (5L) equals 50:1 then I must have died! No matter what size batches you are mixing, 20ml to each litre can be done in your head. Years ago I had a Bingo chart, listing ounces on one axis & gallons/quarts on another, but the damned thing always seemed to be missing when you needed it.
Some day Uncle Sam will find the political balls to implement what the rest of the world uses, & you will wonder why such a good idea was so long coming.

Ok, this thread is entirely hijacked! Unless maybe that Reynolds 21 was built with the metric system.
To continue with the hijack.
Here's the thing, all my life the question I get from strangers is "How tall are you?" The answer, since I was 16 years old, has been 6 ft 7 inches.
If I had been born in one of those ferrin countries who don't understand good ole amerkin feet and inches, what would be the answer?
2006.6 millimeteres
200.66 centimeters
20.066 decimeters
2.0066 meters
0.0020066 kilometers perhaps?
Basketball is pretty popular in some parts of Europe, in the USA it gets mentioned if a team has a "7 footer" in the middle. What's the standard for a really tall player with the metric system?
Hey Hans, did you see that team Europa just signed a 2.1336 meters'r?
Just don't seem right.
Merry Christmas everyone.

You should say "2 metres,& I weigh 16 stone" look them in the eye, or down in the eye I guess and say nothing more. It might be fun to watch the mental gymnastics as they try to figure out what the hell 'yo be takin 'bout boy? I bet they go easy on the "boy".
Merry Christmas to all, wish I could be sailing, the wind at my place was 15kts, but the water was 5C,.. er make that 41F

I've got a 1984 Reynolds 21, and it is a blast!!! I am new to sailing and I have learned (the hard way) that it is a pain in the butt right these boats once you flip them.....
Any chance you could send some detailed pics of your trailer. Mine is in terrible shape and I am having it rebuilt. I'd like to show my trailer guy what it should look like!
It's getting close to spring, do you have yours set to sail?

Unfortunately, I am not up in your area. I live down in Pensacola, Florida. I have not rigged a stereo on mine because I am not convinced that I have the ability to keep the boat upright when I take it out. I take it out on light wind days and my girl loves it. When the winds pick up a bit, I'll grab a few buddies and we tend to push it past our sailing abilities. So, I keep it fairly barebones to minimize the amount of things that can be damaged. Not to mention, I like the peace and quiet out on the water- no music, no motors....

Oh i thought you were in my area, OK but how do you flip this BOAT it is heavy and i do like to go out in 20knts of wind what is the wind conditions your in to flip it! this will be my first sailing season with it! I refuse to get into the water so i will not flip it! But i guess you are getting the hull out of the water? what point does this happen ? How fast is this boat also? thanks! i cant wait to use it on Lake Erie!
