• Metric System is the only standard legal system of Weights and Measures in India.  Remember that use of old units of measures such as Padi, Marakkal, Aazhakku, foot, inch dozen etc is illegal.
  • Ask for price per kilogram, litre, metre etc., and refuse to buy any commodity in terms of old units.
  • Buy in definite metric quantities and not by money worth.
  • Buy your requirements in round metric units, like 10 grams, 100 grams, 200 grams, 500 grams, 1 Kilogram etc.  Avoid the use of the word Kal(1/4) or quarter.  This way your calculations become easier because our coinage is also decimal
