The Tamil units of measurement are a system of measurements that was traditionally used in ancient Tamil-speaking parts of South India.

These ancient measurement systems spanned systems of counting, distances, volumes, time, weight as well as tools used to do so. While modern India uses the metric system, some of these older measurement systems, especially those of counting, are still used today.
Other units that have persisted are those of area – the ma (not to be confused with the dollar-cent) and the ‘ground’, both used to measure land and the molam which has been relegated to measuring the length of a sandanam garland sold on streets.
There are several similarities between the measurement system used in Tamil Nadu and that used by the Indus Valley civilisation. Excavation studies from Keeḻadi reveal existence of an older non-vedic civilisation in Tamil Nadu,[1] and suggest possibilities of ancient Indian mathematicians in Tamil Nadu.[2][clarification needed]
