| 1830/00/00 | By careful examinations of the measuring bars and the two standards, Struve and Tenner are able to convert Russian sajens units of measurement into French toises. Struve will present future results in toises. | Work | Old Observatory University of Tartu | Tartu | |||
| 1855/00/00 | During the summer, Struve's team calculate the length of the quarter meridian that runs from Hammerfest, Norway, through Tartu, to Stara Nekrasivka near the Black Sea and then work out the circumference of Earth to be 40,008,696 metres. | Work | Old Observatory University of Tartu | Tartu |
