In general, conviction means a strong persuasion or belief. it also means the state of being convinced. in law, a conviction is the verdict that results when a court of law finds a defendant guilty of a crime. the opposite of a conviction is an acquittal (i.e. "not guilty"). in scotland and in the netherlands, there can also be a verdict of "not proven", which counts as an acquittal. there are also cases where the court orders that a defendant not be convicted, despite being found guilty.
