While calulating the least count of main scale which was in CM you said it is 1mm i.e. 1/10. Now, in other part you said that if main scale is in mm then the least count of main scale is 10/10 i.e. 1mm.
Will you please clarify this? Why you did 10/10 in mm scale and 1/10 in cm scale?
sir please upload sheets of screw gause and verniar calipers
Sir here the answer will be 0.01mm and 0.001 cm.....
