That's ridiculous. Everyone knows you buy firewood in cords.

Imaging everyone in the world having his own idea of what a Barrel is... That is why the metric system was devised.

The only reason there is no confusion on what the the meaning of "feet" and "inch" is, is that there is only one country left using those measures...

I love it when a plan comes together.

No problem really: everyone just make sure you have satellite internet, so the Google converters are handy. Can't fathom How I'd know about those

Nope. Still used in Marshall Islands and FSM.

You speak too soon ...

There is a unit of measure called the "U.S. Survey Foot." It is almost exactly equal to a standard foot, but it's definition is slightly different:

standard (or "international") foot: .3048 meters
U.S. survey foot: 1200/3937 meters

Apparently some US states survey with one, and some the other ... or they use metres to avoid confusion.

Fixed for you

In everyday usage a simple 1 m/s = 2 knots is close enough

EU uses a decimal based measure(metric) & decimal money (Euros).
But they use commas for decimal points---really!!

However, outside of trading those units are not used. Sizes for tanker cars for example will be given in m3, not in barrels...

In N.A.,wood is sold in cords (128 cu.ft.) (4'x4'x8' just like plywood).
Tanker cars & trucks are labelled in Ltr (44,000L in a highway tanker)

Jim (who is pretty much bi-lingual in matters of units)

A deg. C is close to 2deg F for practical conversion purposes.

Also, the difference between ten knots and twelve knots is not huge, but from three metres per second to four it seems like the difference would be huge. I say 'seems', because I have no idea how 'metres per second' translates into speeds I travel in.

Our Cdn marine forecasts have stayed in knots thankfully.

The 'land people" forecast went to Km/h long ago-but land people don't understand or use wind speed anyway,so no big harm done.

Hint: Just read the land forecast Kmph as Knots & you wil get close to what will actually occur on the water. 30Kmph wil mean 30kts on the East coast of Canada

M/s just ticks me off. There is no logic in wind speed in M/s.
I'm just getting used to Kmh & am able to convert to/from mph in my head using .6 factor.

M/s is easy. Just double it for knots. 2M/s = 4 knots.

I learned this today from two people on the internet.

(One of whom I trust!)

One thing I've learned for sure from reading this thread, is it is a real yarn. There is a lot of dis cord here, and there. Still, it is living proof that there are tuns of fun, whether it is in iambic penta meter meters or knot. While it has been stated several times that people cannot fathom this, no one who says it is out of their depth or fails to measure up. A thumbs up to all, it has been a bushel, er, a barrel, of fun, and shows we all know watts up. Some gave an inch and others took a mile, but it all too more than a New York minute. As in many surveys a chain came up.Just remember knots is a nautical and so are miles, particularly if meters and kilos leave you at sea. Anyway, you are all light years ahead of the rest. But do you think we need to retitle Fahrenheit 451 to something more meaningful. Why even in WW II, some soldiers, and probably sailors too, still had the thousand yard stare.

I am wondering if the convenient rounding up might be the reason for so many displacement hulls having the claimed ability to exceed their calculated hull speed by a bigger margin than one would think possible -even more than an opportunistic current might provide.
