The following precautions should be taken while measuring length with a ruler:
1. The ruler should be kept along the length of the object carefully.
2. Measurement should only be started from a mark that is fully clear. Example: If you measure from 3-cm mark to the 7-cm mark, the length is 4 cm (7 − 3 = 4 cm).
3. Eyes should be exactly above the point where the measurement is to be taken, otherwise you might get faulty or inaccurate readings.
