The United States and other western countries adopt the 6400-bit system, and the Kuomintang's "official" compass also adopts the 6400-bit system. The following secret bits are based on the 6000 secret bit system.
One,
The secret bit is actually a unit for measuring angles. Divide a circle into 6000 equal parts, then each equal part is a secret place. Secret symbols are very special, separating high and low positions with a short line, such as:
1 secret writing: 0-0 1
3 12 secret writing: 3- 12
3000 writers: 30-00
Since a circle (360) is equal to 6000 dense bits, it is easy to know that a dense bit is equal to 0.06 degrees. Convert the secret location into an angle and simply multiply it by 0.06. To convert the angle into dense bits, divide it by 0.06 or multiply it by 16.667.
For example:190 = (190×16.667) ≈ 31-67.
40-05=(4005×0.06)=240 .3
Second,
Use dense bits to indicate the direction angle.
The bearing angle is measured militarily, and the true north is 0 degrees, measured eastward. Represented by the angle system as:
North: 0 East: 90 South: 180 West: 270.
Northeast: 45 southeast: 135 southwest: 225 northwest: 3 15.
Similarly, the direction angle expressed by dense bits is:
North: 0-00 East: 15-00 South: 30-00 West: 45-00
Northeast: 7-25 Southeast: 22-25 Southwest: 37-25 Northwest: 52-25
