Note.— The Meter is the length, at the temperature of 0°C, of the platinum-iridium bar 

 deposited at the International Bureau of Weights and Measures at Sevres, near Paris, 

 France. 



The present legal equivalent of the meter is 39.370113 inches, as above stated. 



The Kilogram is the mass of a platinum-iridium weight deposited at the same place. 



The Liter contains 1 kilogram weight of distilled water at its maximum density (4°C), 

 the barometer being at 760 millimeters. 



* In accordance with the schedule adopted under the Weights and Measures (metric system) Act, 1897.
