In a screw gauge, there are 100 divisions on the circular scale and the main scale moves by 0.5 mm on a complete rotation. The zero of circular scale lies 6 divisions below the line of graduation when two studs are brought in contact. When a wire is placed between the studs, 4 linear scale divisions are clearly visible while the 46th division of the circular scale coincides with the reference line. The diameter of the wire is ______ × 10⁻² mm.
