Technical Architecture: Kilogram Normalisation & Avoirdupois Mass Standards
Converting mass and weight across measurement systems requires anchoring calculations to international metrological standards. In the SI system, the kilogram is the base unit of mass. Khalasna maps all units to exact kilogram ratios using the international avoirdupois definition established in 1959, where 1 pound (lb) is defined as exactly 0.45359237 kg. An ounce (oz) is legally 1/16 of a pound (0.028349523125 kg), a stone is 14 pounds (6.35029318 kg), and a metric ton is 1,000 kg. When a user converts an amount, the engine normalizes the input into kilograms and multiplies by the target scale factor using IEEE 754 double-precision arithmetic. Results are dynamically formatted with floating-point epsilon guards to prevent 0.0000000001 rounding artifacts.
