This Ruby script converts a list of weight values from pounds to kilograms and prints the converted values in a formatted table. It uses the `FormatWeight` module to process an array of hashes containing names and weight data. The code calculates and displays the maximum and minimum weight entries after conversion, relying on the built-in `Float::INFINITY` constant to initialize the search for the lightest object. The program outputs both the full list of converted weights and the identified extremes without using any external visualization libraries.
