The word ‘converter’ refers to a device or software that changes one form of input into another. This can involve transforming data formats, electrical signals, or units of measurement, among other types of transformations. For example, a power converter changes electrical current from one voltage to another, while a file converter modifies a digital file from one format to a different one, such as converting a PDF file to a Word document. In a broader context, a converter can also refer to someone or something that transforms or changes the nature of something.
