Old Russian measures of length
The Russian system of measures is a system of measures traditionally used in Russia and in the Russian Empire. It was standardized on the basis of English measures by the imperial decree of 1835: an inch was entered, a line, a point, a foot, arshin equated to 28 inches, a sazhen to 7 feet, a number of obsolete measures (longitudinal with respect to the verst) were excluded. Later, the Russian system was replaced by the metric system of measures, which was approved for use in Russia (optionally) under the law of June 4, 1899. The use of the metric system of measures in the RSFSR became obligatory by decree of the Council of People's Commissars of the RSFSR of September 14, 1918, and in the USSR by a decision of the Council of Ministers of the USSR of July 21, 1925. Legalized basic relations between the old Russian and metric measures: 1 arshin is 0.711200 meters, 1 pound is 0.40951241 kilograms.
Despite the lack of practical application, the names of Russian measures continue to be used in phraseological and historical research.
The measures and their values are given in accordance with the Regulations on Weights and Measures (1899), unless otherwise specified. Earlier values of these units could differ from those given; so, for example, by a regulation of 1649 a mile was established at 1 thousand fathoms (surveyed) - approximately equal to 2.1336 km, whereas in the XIX century the mile was 500 fathoms; 656 and 875 fathoms were used and were used.
