Answer:
The smallest reading up to which a screw gauge can be measured is called least count of screw gauge. It can be find out by following method; L.C = pitch of screw gauge ⁄ no. of divisions on circular scale i-e 1mm⁄100 = 0.01 mm. The least count error is the error associated with the resolution of the instrument.

Answer:
the pitch of a screw gauge is the linear distance moves by its screw on the main scale when the circular sale is given one complete rotation..
the least count of a screw gauge is the linear distance moved by its screw along the main scale is given ine complete rotation
