Back Azimuth; is the opposite direction of an azimuth. Comparable to doing "about face." To obtain a back azimuth add 180 degrees if the azimuth is 180 degrees or less, or subtract 180 degrees if the azimuth is 180 degrees or more. The back azimuth of 180 degrees may be stated as 0 degrees or 360 degrees. Or divide the compass heading by 30 to get the clock number or multiply the clock number by 30 to get the compass heading. For instance suppose your heading is 60 degrees and you want to know your reciprocal heading/back azimuth. 60 divided by 30 = 2. on a clock, the number opposite 2 is 8; 8x30=240.

ONE FOOT EQAULS ONE MILE SCALE:
This is my scaled visualization system; I can stand on the beach and visualize half the earth at a time or a fire fight at my feet. I have develop speed charts etc. and if given the dimensions and other data can produce a three dimensional view of any situation perfectly proportional to reality.
My math skills are worse than my reading skills I’ve cavemaned all this dividing things in half over and over LOL do not understand decimals etc. Anyways!
Note; when I reached the 1/128th mark representing 3.4 or 3 feet 3 inches my limited math skills reached their limit so I begin to round off the figures. However I would argue that the exact figures would not make enough different to matter. If anyone cares to do the math and share I would like to see them.
Micron or (um). One millionth of a meter. 1000th of a mm, (1000 in a mm). There are 25400 in one inch. 250 um equal 100th of an inch. The human hair is from 75 to 100 um in width. The human egg is 100 um in width, a single human cell 10 (and is considered to be invisible to the naked eye under any conditions). A bacteria 1-2 um. A virus 100 to 1000 times smaller. Now you would be into the Nano world, billionths of a meter. source book titled Germs by Judith Miller, page 43.
1 ft = 1 mile;
1/5000th of an inch = 1 inch to scale. Also 65 microns/um.
1/3968th or (4000th of an inch rounded) AKA 1/32 of a 128th of an inch.
512th = 10 inches to scale AKA a 500th of an inch (rounded off) and or ¼ of a 128th of an inch.
256th = 1.7 feet (125 um) or rounded to 18 inches, AKA 1/50th or ½ of a 128th.
A 128th = 3.4 feet.
1/64th = 6’.8”, 3/128th = 10.2, 1/32 = 13.6, 5/128th = 17 ft., 3/64th = 20.4, 7/128th = 23.8, 1/16th = 27.2 or .6 rounded, 9/128th = 30.6, 5/64th = 34.0, 11/128th = 37.4, 3/32nd = 40.8, 13/128th = 44.2, 7/64th = 47.6, 15/128th = 51, 1/8th = 54.4 or 55 feet rounded, 17/128th = 57.8, 9/64th = 61.2, 19/128th = 64.6, 5/32nd = 68, 21/128th = 71.4, 11/64th = 74.8, 23/128th = 78.2, 3/16th = 81.6, 25/128th = 85, 13/64th = 88.4, 27/128th = 91.8, 7/32nd = 95.2, 29/128th = 98.6, 15/64th = 102, 31/128th = 105.4, 1/4th = 108.8 or 110 rounded.
Formula one person per square yard; got this idea from a standard area per Marine in open ranks formation. 1/16 inch square to scale 27 x 27 feet in reality equals 81 troops. 1/8 inch = 366. 1/4” = 1344. ½” 5377. 1” = 21511. 2” = 86044. 3” 193600. 4” 344,476. 6” = 774,400. 8” = 1.3 million. 9” = 1.7 million. 1 foot = 3.1 million. Note 332 square miles = one billion troops. 1992 square miles = 6 billion or roughly the population of the world.
