How to Convert Base 9 to Base 25

Converting Base 9 (base 9) to Base 25 (base 25) is a core calculation in Radix Number System, which represents numerical values across different positional numeral systems and radix bases. Translating numbers from radix 9 to radix 25 reorganizes polynomial coefficient representations across positional numeral systems. Digits represent coefficients of powers of base 9, which are mapped to decimal (base 10) and reconstructed into base 25.

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (decimal base-10) without arbitrary rounding:

V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)

Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)

1. Source Base Radix Polynomial:

N_{10} = \sum_{i} d_i \cdot 9^i

2. Target Base Radix Division:

d_j = \left( \frac{N_{10}}{25^j} \right) \bmod 25
