Scientific and Practical Metric Units


IN the article entitled “Scientific and Practical Metric Units” which appeared in NATURE of October 24, 1918, reference is made to the convenient bridge to the metric system which exists in the ton, and the author asks for a convenient monosyllabic name for a weight of about 2.2 lb. I would commend for consideration the word “seer.” The Imperial Indian seer, in common use all over India on the railways, weighs 2.05 lb., and would be as convenient a bridge to the metric system for India as the ton would be at home.
