How do you measure the length with a meter scale?

Answer»

The zero marks on the scale are made to coincide with one end of the table and the reading at the point which is coinciding with the other end of the table is taken. 

Since a meter scale has some thickness. 

We may make an error if the eye is not correctly positioned. 

The correct position of the eye is vertically above the end where the reading is to be taken.
