How do you measure the length accurately with a meter scale?

Answer»
  • In our day-to-day work, we use a wooden/plastic scale to measure lengths. 
  • It is marked or graduated in centimeters and millimeters. 
  • Take a scale. The zero mark on the scale is 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 which is vertically above the end where the reading is to be taken.
