In a screw gauge, 555 complete rotations of the screw cause it to move a linear distance of 0.25cm.0.25cm.0.25cm. There are 100100100 circular scale divisions. The thickness of a wire measured by this screw gauge gives a reading of 444 main scale divisions and 303030 circular scale divisions. Assuming negligible zero error, the thickness of the wire is :
