```							Least count of a spherometer depends on the device that you have,
normally in labs , the least count is 0.01mm or 0.001cm
least count = pitch / number of divisions on the circular scale head
normally number of divisons on circular scale head is 100
and pitch is 1mm (i.e. on the linear scale)
so
least count = 1 / 100 = 0.01 mm or 0.001cm

```							the formula of LC is LC=pitch/no of divisions on circular scale and number of divisions are 100(u can check too)and pitch means its complete rotation’s impact which is 1mmso, LC=1/100      =0.01 mm or 0.001 cm

```							Distance  through which the screw advances on the main scale in 10 rotations of the circular scale l=1cm Pitch of the crew therefore p=l/10 =0.1cm Total no. Of divisions on circular scale N=100Therefore Least count =P/N=0.1/100=0.001cm
