Thread: What's a "super metre"

150mm x 25mm rough sawn board-- 1.75 super feet to the metre.

Cheers Andrew

Found this in a previous thread, not sure if that's what you're after but it sounds good to me

How many super metres are in a cubic metre?
I'm familiar with "super feet" from the imperial days, but haven't come across this term before.

Simon,
I've been involved in selling timber for over 20 years and have never before heard of the term super meter. Are you sure in this context it was not "square metres" of a certain thickness?

This figure of 1.75s ft to the metre will only apply if the stock is 150mm x 25mm.

I've been involved in buying it for at least the same time, and I've never heard of it either. Unless you're thinking of building the ark, you won't want 61 cubic metres. It would almost certainly be either square metres of a certain thickness, or linear metres of a particular width & thickness.
My bet is that he's talking about 61 sq. metres x 25 mm (approx. 1"), but it's not a term that I've ever heard before. Best you talk to the designer.

Oops, fingers type faster than brain works

I have lived for almost 41 years. Never heard of it either.

Superman - yes
Supermarket - yes
SuperShytAuto - yes
Supersonic - yes
Super league - yes
Super duper - yes
Super bowl - yes
Superb - yes
Superannuation - yes
super metre - No

Hmm could it be 1m X 1m X 1in similar to 1 superfoot?

Commonly found in fighting games, a super meter increases when either a character takes or gives damage (depending on the game). There are many variations on the super meter, depending on the franchise or game.


? making a super boat?

Thanks for the valuable and, er, invaluable replies!
The page I was looking at was this:
Hartley 16 Trailer Sailer
Click on "site contents", then "tech details" and scroll down to "(C) Metric wood materials list"
If I'd looked at bit harder I would have seen the imperial quantities listed above, so now I know the conversion, but I'm still interested to know the definition of "super metre" and relieved I'm not the only ignoramus on this forum!

Very peculiar. From that official looking website 200 super feet = 61 supermetres. That looks like 3 and a bit under 1/10 superfeet per supermetres. That is the number of feet in a metre. So I deduce that a supermetres is a bastard term equal to a board 12" wide and 1" thick and 1 metre long!

I initially thought a "super metre" might be 1m X 1m X 1cm, but that would give a ratio of 4.23 super feet to the super metre, so that was wrong, as 200/61 = 3.28.
The mystery deepens.
I'll email the company and ask them.

Jeremy has it in one. They've broken rule one when metric conversion came about - don't mix units.

One super foot is 2359.7 cm3
12 in X 1 in X 1 metre is 7741 cm3
Ratio is 3.28, which fits with 200/61
It must be an archeological relic of the moment when old-time timber merchants came up against the metrication police
It's a bastard all right!

This is very odd.

Let's have a go at it.

1 inch = 0.0254m
1 ft = 0.3048m

200 superfoot
= 200 x 1ft x 1ft x 1in = 200 x 0.3048m x 0.3048m x 0.0254m
= 0.472 m3

200 superfoot = 61 super metres
hence,
1 super metre = 0.472 m3 / 61 = 0.00774m3

The only way to use m, cm, inch and ft to make 0.00774m3 is

1ft x 1in x 1m
= 0.3048m x 0.0254m x 1m
= 0.00774m3

SO 1 super metre = 1ft x 1in x 1m

Now thats odd.

I was almost right.
