The metric system of measurements

[JimBuis]

Okay, now that's it!!   If we mill lumber in metric sizes rather than Imperial, the kerf becomes smaller and the lumber is smoother requiring less planing leading to less waste. 8) 8)

Problem solved. ;)  Next subject. :P

[Tom]

But, my trees are in feet and inches.    :-\
Does the nursery sell mm and cm trees now? 

How many inches will a cm tree grow in a season? :P

[dundee]

Tom, as you know, metric is 25mm, imperial 1 inch, metric is smaller, lumber is sold as metric, not imperial---if the 25mm is dressed 4 sides (after KD) the finished width is 18.5mm,

Even length, say 8 feet is 2.4 metric, we do not market 8 feet

[thurlow]

How tall the standard ceiling height be if not 2.4 metric?  ;D

[dundee]

Thurlow, most houses here have a 2.4 stud, for what it is worth, we HAVE to mill for the USA market imperial,  :( I don't want to upset you guy's up there, but I reckon the USA wull change one day  ;D

(waiting for Tom's response)

[Tom]

Wait a minute, I mean... ?? what is a minute in metric?,  Uh..  I was trying to count up the mm's and ran out of fingers.  Y'all have to use a real big number and still have to use fractions.  I don't get it.  :D :D

[SwampDonkey]

I use both all the time. No big issue: 1 inch, 1 foot, 1 meter all different lengths anyway, what's one more to learn.  ;D

But what is neat, maybe not earth shattering, is the fact the 1 litre of water is 1 kg. But, 32 F = freezing point seems more arbitrary than 0 C = freezing point. 1 Imperial gallon is 10 lbs though.  ;) :D

Have fun. 

[thurlow]

I understand.............sorta..............the metric size wrenches, but....................my metric socket wrenches fit on a half-inch drive impact/pull bar/breaker bar/rachet.  No way the "metric countries" use a one-quarter/three-eights/one-half/three-quarter/one inch drive, so what are they.  :P

Is it good that I'm 5'10" (don't know how many km that is) and weigh 15 stone (or is that a whole 'nother system)?

[sawguy21]

Stone is an old English unit of measure but I have no idea what it is in pounds or kilograms. I think asy used the term in another thread so maybe she can enlighten us.
The Brits also measure truck capacity as 'cwt' or hundredweight. Never understood that one either.

[SwampDonkey]

taters are measured and priced in hundred weight to.  ;D

[Tom]

1 imperial gallon is 10 pounds though.

 Holy Cow!, Swampdonkey!

I did some research and some cypering and that's expensive.  That's 19.85 a gallon USD :P

What are you putting in that gallon that costs almost $20? ???

Thurlow, just how much does a stone of wood weigh?
If you find out how many km's you are, let me know.  I'm 5' 9 1/2" so we'll be close.

[sawguy21]

 :D :D :D :D Tom you are a hoot. I sincerely hope that gallon weighs ten pounds and doesn't cost that across the pond.

[Don P]

We hit a rock in the garden that's gotta outweigh me, so I'm a petite, less than one stone  ;D.

Where the fractions get me into trouble is in something like a stair or rafter cypher. Say I've got 108-5/16" rise and need to get 15 risers in that height.
Convert to 108.3125
divide by 15 = 7.2208"
Convert back to fractions= is about 7-7/32
That took several minutes and had several extra chances for error. Now when I lay out, if I just step off at 7-7/32's there will be a cumulative error of several thousandths per step that will all come to fruition at the top step.

With metric you aren't bouncing back and forth.

That said, my brain divides things in fractions. Halves, quarters, eighths, those are natural to me, but I grew up thinking that way  ???.

[Don_Papenburg]

SD , If a litre of water is also a Kg of water why bother with litres? Is Kg an abreviation for Keg?

[Dave Shepard]

A hundred weight isn't always a hundred pounds though. Ask a blacksmith why 1+2+3=171 pounds.


Dave

[Tom]

Yeah, I know.  Those potatoes are heavy.  I've tried to pick some of them up before. They must weigh at least a hundred pounds.  ;D  They need to keep those potatoes in 50 lb sacks. 


......... I didn't mean that.  King Edward said Sacks are 364 lbs.  There's no way I could manage that many potatoes. :D

How much does a hundred pounds of iron really weigh? :P :-\

You'd think that Kg could stand for Keg but my research says that a Keg is a Hectoliter.  *hectolitre if you're from somewhere else than the USA.  I didn't know that costa Rica was going to enter into this discussion.  I wonder if our friend Hector had something to do with the capacity of a keg  Hectoliter might just be a Tico bucket of some sort or another. It might have something to do with possession too, as in, "That's Hector's Liter". :-\

[TexasTimbers]

I could be wrong, but I think a knot is a knot in any hemisphere. If so, we have found some common ground. Also Wombats are fairly reliable in their nature. They move and grow and live in a very predictable way. We could measure everything in Wombat Knot Units of Measure (WOKUMs).

How much milk ya got in that jug Billy Bob?

About 21.7 Wombat Knot Units worth.

How do ya figger?

Well, there is exactly enough milk in here to give a standard sized Wombat enough energy to walk 50 miles at and average speed of 21.7 knots.

Oh. What is an average size Wombat as used in the universal measuring system now?

An average sized Wombat = 39 Wombat Knot Units.

How old is that Wombat?

7920 Wombat Knot Years.

How do you figger?

The average Wombat lives on average a length of time to have consumed enough energy to have maintained an average speed over a 50 mile distance of 7920 Knots when condensed in Wombat Relative Time Units (WORTUs).

How much does that battleship your son is assigned to, weigh, Fred?


It's about 1.687 WOKUMs.

How do ya figger that?

It displaces the same as 1,687,272.73  fully grown submerged Wombats.

See everything would be much simpler if it were related in WOmbat Knot Units of Measure (WOKUMs). Armadillos would be too confusing and would not have the same ring to it.

Just take a look at the awesome power of the USS Wombat! 8)


It's true. I let my prescription lapse again. ;;)

[dundee]

Kev, Please take your pills mate  ;D

[Dave Shepard]

Crikey!



Dave

[Don P]

Speaking of sneezing, is a kiloton metric or english?

[WDH]

Its atomic.

[SwampDonkey]

How many lbs in a tonne?  ;D

[Don P]

I dunno, but that sure looks like a long way to spell ton  ;D

[Tom]

I don't know about a tonne because we don't have any here.   A ton is 2000 pounds.  Maybe somebody is trying to invent something new.

[TexasTimbers]

And a ship ton is about a 1/10th more even than a standard ton. It's 2240 pounds also known as a long ton. Unless of course you are dealing with the Chinese, because they are going to short you on your long tons and you'll be out of some tonnage.

A long ton is also equivalent to roughly 777.77 WOKUMs, except in the Horse Lattitudes. Then it's measured in HOKUMs.
