Conversion is a term used to describe the change from one form, state, or concept to another. Synonyms for conversion include transformation, alteration, metamorphosis, modification, transmutation, and transfiguration. These synonyms are often used interchangeably, yet each has its own subtle distinction. For instance, transformation suggests a radical change, alteration implies a slight change, whereas modification connotes a change that affects a whole but retains its identity. Transmutation suggests a change in substance, and transfiguration implies a change in appearance. The choice of synonym depends on the context of use, but all convey the idea of change, transition, or progression.
