Technical Architecture: Base-Unit Normalisation & Dimensional Analysis
Converting heterogeneous measurement units requires dimensional analysis and base-unit normalization. Rather than maintaining N * (N - 1) pairwise conversion formulas for N units, Khalasna uses a hub-and-spoke normalization architecture. For each physical dimension, an international standard base unit (SI) is established (meters for length, kilograms for mass, square meters for area, seconds for time). Every unit is defined by a precision floating-point scale factor relative to the base: Value_base = Value_source * Scale_source + Offset_source. The target value is then calculated via inverse projection: Value_target = (Value_base - Offset_target) / Scale_target. This design handles linear conversions (meters to feet: 1 m = 3.28084 ft) as well as affine conversions with non-zero offsets (such as Celsius to Fahrenheit: (C * 9/5) + 32). All arithmetic runs locally using JavaScript Number primitives, ensuring microsecond response times.
