Prefixes are formed by combining one or more affixes for the power represented by the prefix, and an infix that shows if the exponent is positive or negative;
The symbols for the prefixes are the combination of the first letter of each digit affix, uppercase when the exponent is positive, lowercase when negative;
Alternatively, the symbols can be written as the exponent as a superscriptr sequence of digits, without any signal, for positive exponents, or as a subscriptr sequence of digits, without any signal, for negative exponents;
So, for each digit of the exponent, we will combine the following:
| Digit | Affix | Positive Exponent Symbol | Negative Exponent Symbol | ||
|---|---|---|---|---|---|
| Letter | Superscript | Letter | Subscript | ||
| 0 | shun | Sdrv | 0drv | sdrv | 0drv |
| 1 | eka | Edrv | 1drv | edrv | 1drv |
| 2 | di | Ddrv | 2drv | ddrv | 2drv |
| 3 | tri | Tdrv | 3drv | tdrv | 3drv |
| 4 | cha | Cdrv | 4drv | cdrv | 4drv |
| 5 | pan | Pdrv | 5drv | pdrv | 5drv |
| Positive Exponent Infix | Negative Exponent Infix |
|---|---|
| ma | ti |

Conversion to and from SI prefixes
Number Shastadari_Prefix Unit ↔ Number SI_Prefix Unit
Find the exponent for the Shastadari_Prefix, Shastadari_Exponent, and for the SI_Prefix, SI_Exponent;
With those two exponents, find the correspondent factor of conversion, using the following formulas:
| Factor to SI | Factor from SI |
|---|---|
|
10Shastadari_Exponent ÷ 14SI_Exponent 6Shastadari_Exponent ÷ 10SI_Exponent |
14SI_Exponent ÷ 10Shastadari_Exponent 10SI_Exponent ÷ 6Shastadari_Exponent |
Finally, multiply the original number by the calculated factor;
Since the SI prefixes are less granular, we can create a mapping for which Shastadari prefix can accommodate all the magnitude expressed by a SI prefix, or, in other words, which Shastadari prefix is roughly equivalent to which SI prefix:
