The centipawn is the unit of measure used in chess as measure of the advantage. A centipawn is equal to 1/100 of a pawn. Therefore, 100 centipawns = 1 pawn. These values play no formal role in the game but are useful to players, and essentials in computer chess, in order to evaluate positions. The pieces have usually an integer value in pawns, but using the centipawn allows strategic features of the position, worth less than a single pawn, to be evaluated without requiring fractions.
