Abstract: The ladder convertible to a scaffold is a self-standing ladder that is able to convert into a scaffold. The self-standing ladder is constructed of two ladder members that are able to attach to and pivot with respect to one another via a removable cap. The two ladder members also attach to one another via a foldable platform, which provides support when the two ladder members are pivoted away from one another in a self-standing configuration. The two ladder members may be disconnected to one another, and held in parallel arrangement with respect to one another via the foldable platform. The foldable platform is able to span a scaffold length between the two ladder members in order to form a scaffold. A pair of guar members attach to the two ladder members to provide guide rails on opposing sides of the scaffold.
