That’s certainly easier to remember than the length of your foot (I wear size 12, a foot long. No idea what that is metric, maybe something in the 40s. It’s size 29 in “mondo” (ski boots).
That’s what I do; multiply the m/s by two to get kts., which is what I’m used to think in when it comes to wind speed. Could that be because of my seafarer background?
Anecdote:
On a J/U rig in the Java Sea we were Waiting on Weather (WOW) to move during the NE Monsoon.
The Companyman came up to the Jacking Control Room, looked out at the wind sock and said; “stiff as a preacher’s dick in a double wedding. We ain’t moving nowhere today”.
Then he went back to his office and his game of Solitaire.
PS> Difficult to find a conversion table with that wind speed measuring unit.
Is it a ploy to confuse the enemy?
Something like using Navajo natives to communicate in their native language during WWII.
Nobody understood what the hell they were talking about either.
The standard unit for pressure in the SI system is the Newton per square meter or pascal ¶

The SI unit of force is the newton, symbol N.
Force is defined as the rate of change of momentum. For an unchanging mass, this is equivalent to mass x acceleration.
So, 1 N = 1 kg m s-2, or 1 kg m/s2.

I think the Navy is hooked on “yards” because of the close equivalence of 1 nautical mile (6067 ft) to 2000 yds., which makes it easy to mentally convert ranges from yards to miles. I say that because in my limited experience observing on Coast Guard Cutter bridges (which I got to do every now and then in the PHS), I seem to recall that I rarely heard a range called in anything but a multiple of 500 yds (¼ mile). I’m not sure, but I’d guess that the rings on their radar scopes and maneuvering boards or screens are marked at 500 yd intervals.
Even the inch is a metric unit these days, defined as 25.4 mm. Is there actually a single imperial unit out there that are not defined as some conversion of a metric unit?
The majority of U.S. customary units were redefined in terms of the meter and kilogram with the Mendenhall Order of 1893 and, in practice, for many years before.[2] These definitions were refined by the international yard and pound agreement of 1959.[3]
Interesting quote from the Containertech article Ombugge posted in the other thread: " The overwhelming need to have a standard size for containers, in order that they fit all ships, cranes, and trucks, and the length of time that the current container sizes have been in use, makes changing to an even metric size impractical."
That might be applied to other areas of endeavor as well.
Before you ask.
The SI unit for Volume is Cubic Meter:
PS> The Metric System us not the same as the SI System.
In the Metric system the base unit for weight is Gram and for volume it is Liter and for distance it is Meter.
Interestingly, one Liter of distilled water at 4C weigh 1 kg = 1000 Gram, which fits into a container that is 10 x 10 x 10 Cm. = 0.001 Cbm., or 1 m.t…
So if you can visualize a meter, understand Latin numbers and the decimal system, you got it.
No need to remember all those conversion figures to get it into Imperial and/or US Customary units, which is also different. (Refr. Imp.Gl. vs. USGl.)
