...The survey for (1) was carried out from Barcelona, Spain, just east of Paris to Dunkirk on the Dover coast, and was completed by Delambre JBJ Delambre and Mechain PF A Méchain, who were plagued by the turmoil of the revolutionary period, over six years from 1792. Meanwhile, the experiment for (2) was started in 1792 by chemist AL Lavoisier and steadily progressed with the cooperation of crystallographer RJ Haüy, but was interrupted in 1794 when Lavoisier was executed. It was resumed two years later by Lefèvre-Gineau and Fabbroni, who approved the selection of the mass unit "at the temperature at which the density of water is at its maximum" rather than "at the temperature at which ice melts" and the change of the name from grave to kilogram, concluding in 1799. The standards created based on these findings and kept in the French Archives (Archives) were called the "Archives metre" and the "Archives kilogram." *Some of the terminology that mentions "Lefèvre-Gineau, L." is listed below.
