The conventions adopted for GDA are meant to accommodate greater
density of information display without use of italics, subscripts,
superscripts, multiple fonts, foreign language symbols, or graphics.
If half of the 52 symbols used for English might later be deemed
ambiguous in shape, there are still many more than ([26]^3) label
possibilities available for up to three symbols in brackets:
[Gye] = Gyromagnetic ratio of the electron, [4Pi] = Four times Pi,
[qD0] = Atomic unit of electric quadrupole moment, [p] = momentum,
[c^2] = Square of speed of light, etc.
If four letters are used to identify a unit, then with or without
parentheses, brackets, braces, or slash marks these rules can apply
AND be used in conjunction with established standards of expression:
1. A capitalized first letter means a positive exponent, if the
first letter is not capitalized then the unit has a negative power.
2. Numerals in the second and third positions of the four letter
unit label denote the numerator and denominator of the fractional
power to which the unit is raised, and lack of a numeral in either
internal position correlates to the presence of numeral one:
