Tamil Measuring Units

Measurements in ancient Tamil land were of seven kinds. They were number counts, balance weights, fluid volumes, grain volumes, length, time and the likeness. Ancient tamils were used only mind-calculation for their daily necessaries. Their life is mixed up with calculation for everything. They have enough tables of units for all kind such as weighing, counting, measuring, etc.,. which is similar to the Indus Valley Civilization. They have fractional tables which includes divisor of 2, 5, 8 & etc.,. 

The Tamil peoples are using still their basic unit of distance measurement called muzham to measure the length of jasmine garland. Ancient tamils also used muzhakkuchi (scale/tape) which is the basic measuring instrument to build a temple or other building. One of the temple which used muzhakkuchi is Tanjore Big Temple from Tamil Nadu, India. 

UNITS OF TIME IN ANCIENT TAMIL HISTORY
