Metric Measuring

Speaking of Mils, that reminds me of Land Nav in the Army.   I don't recall exactly, but there are something like 15 mils per degree on the compass? I never thought to ask "why" thirty years ago when I was only 18 and just trying to get by.

Oh my, that mil changes depending who you ask. Interesting wikipedia page on that http://en.m.wikipedia.org/wiki/Angular_mil

Paul, that was an interesting read.
 
For doing conversions on an iPhone, I use this:

allRPNCalc

It's basically a simulator of the HP 21 C (I think?) calculator and features RPN input as well (Reverse Polish Notation - 12 displays 3).

The only real way to enter formulas on a calculator.

It has a conversion mode which lets you select to and from and go in both directions. I leave mine on "in" and "mm".... ;)
 
Convertbot is also good. It will convert a large number of things I think it was .99
 
A mil is shorthand for milli which is French
/Latin for a thousand. So in Imperial it is one thousandths of an inch, and in metric one thousands of a meter, hence 1mm. Makes sense to me.

That's quite interesting din't know it was from Latin.

No special reason for us in NZ and OZ saying "k's" instead of kilometres e.g. 50'ks to the next town, simply easier. We like to shorten everything, except Peter jackson, he likes to extend everything! Do you guys in Europe say k's? I doubt the Germans do.  [unsure]
 
Fredrik,
That is it!!!!!

I sent an email to them, but it had to be in english.

If just happen to be coming to NYC in the next few months, I'll sweeten the deal. If you pack four extra of these in your luggage, I'll pay for the rulers, three rounds of drinks, and dinner at a reasonably priced Manhattan restaurant.

Does this entice you to travel? hahahaha.

Seriously, that is exactly what we are talking about.

I believe the "mils" refers to the number of angular mil radians in a degree.  Radians are used in other areas of mathematics because it expresses the angle in terms of the relationship of of the radius of the circle.

It is also used for computing artillery trajectories. It might be needed to be communicated form FO to a fire comm

See Angular Mil for some history of it.

This is not to be confused with Minute of Arch. MOA, or millimeters or miles.

There is tru and interesting story about programming a satellite navigation system and one programing used miles while another use kilometers in their programing. They still have not found that bird.

Nice to participate and read a thread discussing metric and imperial measurement where no one (including me) has felt the need/desire to get 'on their high horse' about one system over another. Just some shared interesting discussion.  [smile] [cool]

Imperial is better !!!  [tongue]

Metric RULES !!!!  (pun intended)  [ban]

Good post and a great link. To simplify..a "mil" is the angle created in a right triangle with  base of 1000 miters(kilometer} and a height of 1 meter. Approx. 6400 mils to a circle. Yes, it is the basis of artillery calculations. Military maps were/are printed in metric...angles are metric and distance is metric.

We referred to a kilometer as a "klick"..therefore 8 klicks is about five miles. In FO terms....add 800, right 400 was in meters(adjusted from the previous round.)

Ft. Sill, Okla was and is the Artillery Capital of the World. I was there in 1967 and 1968. Fun! Blockhouse Signal Mountain is know to Artillerymen all over the world.

Is this what you are looking for?

If so here is supplier.

If they can't send to the Us maybe I can help you.

The link is in Swedish so you have to use Google translate

http://byggkatalogen.byggtjanst.se/relekta_as/c119718/

Using Google Image Search, I was able to find the manufacturer and an English page. May help someone locate it or one of the US dealers to import some?

It's called the Meterex LongLife® All in One G52 / 2m

There's also a Youtube video linked from the original site posted by Fredrik (non-English).

Depending on price I'd be in for one or two. So who's gonna coordinate the group buy?

Good detective work, Garry!  I wish I had known about this before my friend moved back to the US after his tour of duty in Germany!

I just wrote the company. Hopefully I'll get an answer soon.

If it helps, I would be interested in obtaining at least one and maybe two depending on the price.
 
I spoke with Tom about this earlier today.  If any of you have been looking for a metric rule with extension, let Tom know and hopefully we can get enough orders together to make it happen.
 
I just got an introductory email from their CEO.

I can make it happen, I'm just trying to find out how much, how long, etc...
