What r the precaution which should be taken using a meter scale to measure the length of the object
  • 1 answers

Meghna Thapar 6 years ago

If the object is straight, we can either use a metre scale or a measuring tape to measure its length but if the object is round we have to use a measuring tape to measure its length.

 

Precautions while using a scale:

  1. The scale should be placed parallel to the side of the object being measured.
  2. While reading the scale, the eye must be placed vertically above the scale mark being read.
  3. If the scale has a damaged zero mark or broken left end, measure the length of an object starting from 1 cm mark of scale and then subtract 1 cm from the reading taken at the right end to get the actual length of the object.
