Understanding Unit and Currency Conversions

Mathematical unit conversion involves dividing or multiplying values by exact constants (e.g., converting meters to miles involves dividing by 1609.344). Temperature conversions require offset calculations (e.g. Celsius to Fahrenheit: °F = °C * 1.8 + 32).

Currency exchanges, however, are highly volatile and rely on real-time global trade market averages. This converter pulls data from open-source currency averages. By caching rates daily in browser localStorage, the converter operates instantly on subsequent page requests without hitting the network API, keeping the application lightweight.
