A metering unit for metering a substance, in particular a powder, comprising a storage container for storing the substance and a metering device rotatable about an axis of rotation, a discharge opening being provided for discharging the metered substance, is described as fulfilling higher demands of metering accuracy in comparison with the related art. This is achieved by the fact that at least one closing element is provided on the lowest end section of the metering device for completely closing the discharge opening.
