The hexadecimal quintillion equals 2 100,  just like 2 - 100  is one hexadecimal quintillionth. Long live the good old long scale of zillions !

Example :  The exponentiation expression bi mir-bebi means one million to the power of seventeen :  B × M BB   =   1, 048 576 17  =  2.24 × 1, 000 000 17  =  2.24 × 10 102 .

The decimal googol  (= 10100)  is  BPFC ×  M H :   Almost, one thousand two hundred forty-ten hexadecimal sexdecillion.

1616  equals  BQ × M V :   Onety hexadecimal trillion different integers can be encoded on 64-bits.  That is Sissa's number.

 The 64-bit "Sissa"- register : W WWWWW WWWWW WWWWW

Example :

 Nicolas Chuquet's example number : 745 324,  804 300,  700 023,  654 321 =   745 324 trillion, 804 300 billion, 700 023 million, 654 321 units. Hexadecimal, with IBM digits : 0x  9DD42, 37B63, 6E67B, 207B1 Hexadecimal, with omni-literal digits : JYYFP, VDGSV, SXSDG, PQDGB Juyoyafepi ma, vudogasevi me, suxosadegi mi, pu(qo)dagebi. Enunciated as  universal hexadecimal numerals. Ninety-thirteen thousand, thirteen hundred, forty-two trillion, thirty-seven thousand, eleven hundred, sixty-three billion, sixty-fourteen thousand, six hundred, seventy-eleven million, twonety thousand, seven hundred, eleventy-one. Enunciated as  English hexadecimal numerals.

Note :  Obviously, by using the universal hexadecimal numerals, all consonants and all vowels must be pronounced by respecting the rules of the hexadecimal alphabet.

The hexadecimal googol (= 16 256),   put for example as  be mi mur-ci :  BQ  ×  M  ×  (MZ) C   =  1.798  × 10 308  seems to be the last reasonable limit in numbering.

In SMH, the multiples and submultiples of units have symbols.
These symbols are acronyms, to read in a specified manner.

Since the prefix hexa expresses the magnitude zero, i.e. 10240,
hexa is unequal sixteen. Thus, also its rank zero equals one.

Item, the five ranks of mega are multiples to powers of sixteen.
The first rank is rank zero, sixteen power zero :  Mega  ×  one.

Conclusion :

Just like commonly the acronymic symbols of decimal SI are
enunciated in their full meaning, that is also effective with the
SMH units. Example :  MHz is pronounced  " megahertz ", so
MiHz is always said :  " mega-i-Hertz ",  never  " mi Hertz ".

Nor it is correct to pronounce symbols for units like milli-i-timple : " mit "

as a word ; since this makes no difference between milli-i- and mega-i.

In SHOL, self-evident, there are 16 number-digits :

B  to  W  and  Q.

Only two other letters are auxiliary digits :
 H as one-digit-base = BQ = 16 M is the superbase = B,QQQQQ = 1, 048 576

The universal number names

are all in the same pattern :

7  =  7 × 16 0  =  D × H Q :  di

64  =  4 × 16 1  =  F × H B :  fe

1024  =  4 × 16 2  =  F × H P :  fa

4096  = 16 × 16 2  =  H × H P :  ha

1024 4  =  M ×  M 1  =   M × M B :  me

 *  " weka "  is not BIPM-official.  However :  According to an existent proposal :  1000 10  is " W + deka = weka ", after 1000 9, " X + nona = xona ". BI-SMH now recognises these two proposals of Jim Blowers,  like " xonto " and " wekto "  ( 1000- 9  and  1000 -10 ) . All extentions above are reject .

 The both auxiliary digits, H & M, are used in the both variants of the hexadecimal exponential notation. Example : 7.256  × 10 6    =     S.xgt  × H Z    =    S.xgt  × M B Decimal :   seven point two five six, ten to the sixth power equals hexadecimal :   six point fourteen eleven eight, sixteen to the fifth power. Naturally, sixteen to the fifth power is a (hexadecimal) million to its first power.

  If in Greek language nine is doubtless εννέα, ennéa, there is an existent tradition in science to prefer exceptionally the latin prefix nona.

So for example, IUPAC decided in 1957, to use always " nona- " instead of  " ennéa- ".  See :  nonane and nonanol. (No "very correct" ennéane).
