The centipawn is the unit of measure used in chess as representation of the advantage. A centipawn is equal to 1/100th of a pawn. Therefore 100 centipawns = 1 pawn. These values play no formal role in the game but are useful to players, and essential in computer chess, for evaluating positions.
The top computer move will lose zero centipawns, but lesser moves will result in a deterioration of the position, measured in centipawns.
This value can be used as an indicator of the quality of play. The fewer centipawns one loses per move, the stronger the play.
