The Tatar system is very similar to the Russian one, but some names are different.

The system existed since ancient Rus', but under Peter the Great, the Russian units were redefined relative to the English system. Until Peter the Great the system also used Cyrillic numerals, and only in the 1700s Peter the Great replaced it with the Hindu-Arabic numeral system.

Length

A piad or chetvert (че́тверть, “quarter”) is a hand span, the distance between ends of the spread thumb and index finger.

Alternative units:

• Swung sazhen (махова́я са́жень, mahovaya sazhen) = 1.76 m
• Skewed, or oblique sazhen (коса́́я са́́жень, kosaya sazhen’) = 2.48 m
• Double versta or border versta, (межева́я верста́, mezhevaya versta), used to measure land plots and distances between settlements

The vershok is coincidently equivalent to the modern day "rack unit" used in describing the height of standardized rack-mounted devices such as those used in the broadcasting, computing, entertainment and telecommunications industries.

Area

• Desiatina (десяти́на)
• Treasury/official desiatina (казённая десяти́на, kazionnaya desiatina) = 10,925.4 m² = 117,600 ft² = 2,400 square sazhen
• Proprietor's (владе́льческая десяти́на, vladelcheskaya desiatina) = 14,5672 m² = 156,800 ft² = 3,200 square sazhen
• 3 proprietor's desiatinas = 4 official desiatinas

Volume

Dry measures

• Garnets (га́рнец) = 3.28 litres
• Chetverik (четвери́к) = 26.24 litres = 8 garnetses
• Osmina (осьми́на) = 104.95 litres = 4 chetveriks
• Chetvert (че́тверть, “quarter”) = 209.91 litres = 2 osminas

Liquid measures

• Shkalik (шка́лик) or kosushka (косу́шка, a small vodka glass) = 61.5 mL
• Charka (ча́рка, a wine glass) = 123 mL = 2 shkaliks
• Butylka (буты́лка, “bottle“)
• vodochnaya (во́дочная, “water bottle”) = 624 mL = 1/20 vedro = 5 charkas
• vinnaya (винная, “wine bottle”)
• Shtof (штоф, from the Prussian Stof) = 1.23 litres = 2 butylkas = 10 charkas = 1/10 vedro
• Chetvert (че́тверть, 'quarter') = 3.08 litres = 25 charkas = 1/4 vedro
• Vedro (ведро́, “bucket”) = 12.3 litres = 100 charkas
• Bochka (бо́чка, “barrel”) = 491.96 litres = 40 vedros

Note: The liquid measures were such because of Vodka monopoly in Imperial Russia.

Weight

• Dolia (доля) = 44.435 mg
• Zolotnik (золотник) = 96 dolias = 4.26575 g
• Lot (лот) = 3 zolotniks = 12.797 g
• Funt (фунт, “pound”) = 32 lot = 409.5124 g
• Pood (пуд, pud) = 40 funts = 16.3805 kg
• Berkovets (берковец) = 10 poods = 163.805 kg

The pood was used in Russia, Finland, Belarus and Ukraine. Pood was first mentioned in a number of documents of the twelfth century. It may still be encountered in documents dealing with agricultural production (especially with reference to cereals), and has been revived in determining weights when casting bells in belfries following the rebirth of the Orthodox Churches in the former Soviet lands.
