A measuring rod is a tool used to physically measure lengths and survey areas of various sizes. Most measuring rods are round or square sectioned; however, they can also be flat boards. Some have markings at regular intervals. It is likely that the measuring rod was used before the line, chain or steel tapes used in modern measurement.

Rulers made from ivory were in use by the Indus Valley Civilization in what today is Pakistan, and in some parts of Western India prior to 1500 BCE. Excavations at Lothal dating to 2400 BCE have yielded one such ruler calibrated to about Ian Whitelaw (2007) holds that 'The Mohenjo-Daro ruler is divided into units corresponding to and these are marked out in decimal subdivisions with remarkable accuracy—to within . Ancient bricks found throughout the region have dimensions that correspond to these units.' The sum total of ten graduations from Lothal is approximate to the angula in the Arthashastra.
