World unit, or wu for short, is a unit of measurement for distance used in the Blam engine, the engine used for all first-person shooter Halo games. One wu is equivalent to 10 feet (3.05 m).[1]

Most measures of distance in the games, for instance red reticle range, are specified in world units internally, despite metres being used in player-facing HUD elements such as objective markers.
