How does one convert that to ft. at 1000 yds?

Now we have two answers. The first comes to 446 ft and your's to 408.
See why I'm asking?
John,
446 ft FOV is correct, for 1000 meters! However 1000 meters = 1094 yards!!
If you want to state the FOV in yards, you have to multiply the 446 by .9144 factor (1 yard= .9144 meter).
When wanting to covert as you asked, the quickest and easiest way is to just multiply the FOV meters statement by 3, and you will have an accurate FOV conversion in feet!
In reverse, to convert 408ft @ 1000yds, divide 408 by 3 = 136 M @ 1000 Meters!
Confusing, yes! :-C
HERE's a tool that might help in the CCC (consistent conversion confusion)?! With the on-set of my CRS, little cheating tools like that help a lot!! :t:

408 is a fairly good FOV, say 7.8 degrees, and in the range for a 8X32 glass, I hear they (GPO) are well built.

Lee,
Because Pi is constant you only need to compare the radius (or diameter) squared. I can never remember past the third decimal place for Pi anyway.
I find this link useful for converting linear distances into angles, and vice versa.

It's good for other things as well, like maximum AFoV from the ER and eye lens diameter, visual acuity, optical resolution and other stuff.
