Convertir means ‘to convert’ and convertirse means ‘to become, to turn into, to convert to’. Convertirse is the reflexive form of convertir, so it always takes a reflexive pronoun – me, te, se, nos, os or se – that matches the subject. The verb itself is conjugated the same way: in the present tense, yo convierto becomes me convierto. In the affirmative tú imperative the pronoun attaches to the end of the verb, so convierte becomes conviértete.
