The formula to calculate the magnification with extension tube is. length of the extension tube / focal length of the lens + the maximum magnification of the lens. This applies only when the lens is focused at the closest focusing distance, i.e, at the maximum magnification. --.

The Canon extenders will not physically mount to an EF-S lens. Even if you defeat the keying the front part of the EF 2X (any of the three successive versions) would extend into the rear of the EF-S 55-250mm and almost surely contact and damage the rear lens element or the front element of the extender or both, at least at certain focal length and focus distance combinations.
