Tamil units of measurement


The Tamil units of measurement is a system of measurements that was traditionally used in ancient Tamil-speaking 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 International System of Units, some of these older day measurement systems, especially those of counting, are still used today.
Other units that have persisted are those of area – the 'ma' 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. Recent excavation studies from Keezhadi reveal existence of an older non-vedic civilisation in Tamil Nadu. New discovery suggest possibilities of source of ancient Indian mathematicians in Tamil Nadu.
