Use integer affine transformations for unit conversion
Conversion factors are stored as integer Numerator/Denominator pairs. ConvertUnitValue combines source and target factors over a common denominator and delegates to ApplyUnitConversion, which computes (value × numerator + offset) / denominator using Number arithmetic.

<h1>Supplemental Unit Conversion Factors</h1>
131+
<p>The following tables define additional unit conversion factors for locale-specific and regional measurement systems. These tables supplement the Unit Conversion Factors tables defined in the base specification and are searched by GetUnitConversionFactor in the same manner.</p>
