- The number representing the population, expressed in millions, shall be multiplied by the coefficient three for states in which the use of the metrical system is obligatory;
- by the coefficient two for those in which it is optional;
- by the coefficient one for other states.
The sum of the products thus obtained will furnish the number of units by which the total expense is to be divided. The quotient will give the amount of the unit of expense.

The expense of constructing the international prototypes, and the standards and test copies which are to accompany them, shall be defrayed by the high contracting parties in accordance with the scale fixed in the foregoing article.
The amounts to be paid for the comparison and verification of standards required by states not represented at this convention shall be regulated by the committee in conformity with the rates fixed in virtue of article 15 of the regulations.
