The pitch of an error free screw gauge is 1 mm1 \mathrm{~mm}1 mm and there are 100 divisions on the circular scale. While measuring the diameter of a thick wire, the pitch scale reads 1 mm1 \mathrm{~mm}1 mm and 63rd 63^{\text {rd }}63rd  division on the circular scale coincides with the reference line. The diameter of the wire is:
