Length is one of the fundamental physical quantities. A ruler is used to measure the length of an object. It is also used to measure the length of a straight line. A non-stretchable string or thread is used to measure the length of a curved line.
Procedure to Measure the Length of an Object (or) a Straight Line
Procedure to Measure the Length of a Straight Line Using a Damaged Ruler
Procedure to Measure the Length of a Curved Line
When noting the reading on a ruler, you should look at it with the eyes directly above the reading, and not in an oblique way. Otherwise, you will not be able to note the reading accurately. If the zero mark of the ruler does not coincide with the first end of the object, then the difference between the readings at the two ends gives the length of the object.
