The decimal progression of all the French weights and measuresrenders it only necessary to change the decimal point in order toconvert one into the equivalent of any other of the same species andnumerically the same, but of a different denomination. Thus as 9litres are equal to 15.5817 ale pints, 9 hectolitres will be equal to1558.17 ale pints ; and so of the rest.
