Russian units of measurement

The basic unit was the Russian ell, called the arshin, which came into use in the 16th century. It was standardized by Peter the Great in the 18th century to measure exactly twenty-eight English inches (71.12 cm). Thus, 80 vershoks = 20 pyad's = 5 arshins = 140 English inches (355.60 cm).^[2]

Apyad' (пядь, "palm", "five") or chyetvyert' (че́тверть, "quarter") is a hand span, the distance between ends of the spread thumb and index finger.^{[citation needed]}

Alternative units:

• Swung sazhen' (маховая сажень, makhovaya sazhen', distance between tips of arms stretched sidewards) = 1.76 m
• Skewed, or oblique sazhen' (косая сажень, kosaya sazhen', distance between tip of a raised arm and a tip of an opposite leg slightly put away) = 2.48 m / 2.4892 m to be exact, since 1 Kosaya Sazhen is equal to 3.5 Arshins which is equal to 98 inches
• Double vyersta or border vyersta, (межевая верста, mezhevaya vyersta), used to measure land plots and distances between settlements = 2 vyerstas (comes from an older standard for vyersta)

• Desyatina (десяти́на, "a tenth" or "ten"), approximately one hectare
  • Treasury/official desyatina (казённая десяти́на, kazyonnaya desyatina) = 10,925.4 m² = 117,600 sq ft = 2.7 acres = 2,400 square sazhen'
  • Proprietor's (владе́льческая десяти́на, vladel'cheskaya desyatina) = 14,567.2 m² = 156,800 sq ft = 3,200 square sazhen'
    • 3 proprietor's desyatinas = 4 official desyatinas
• Soha (соха, "big plow")

As in many ancient systems of measurement the Russian distinguishes between dry and liquid measurements of capacity. Note that the chyetvyert' appears in both lists with vastly differing values.

Two systems of weight were in use, an ordinary one in common use, and an apothecaries' system.

The pood was first mentioned in a number of documents of the twelfth century. ^{[citation needed]} 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.

The Imperial Russian apothecaries' weight was defined by setting the grain (Russian: гран) to be exactly seven-fifths of a dolya. The only unit name shared between the two was the funt (pound), but the one in the apothecaries' system is exactly seven-eighths of the ordinary funt.

The obsolete units of measurement survived in Russian culture in a number of idiomatic expressions and proverbs, for example:

• Слышно за версту: (It) can be heard a verst away – about something very loud
• Бешеной собаке семь вёрст не крюк: 7 versts is not a detour for a mad dog – about excessive energy or hassle
• Милому дружку семь вёрст не околица: 7 verst is not too far for a darling friend
• Верста коломенская: Kolomna verst – about a very tall and slim person (in this case the reference is to the verst pole road mark: verstovoy stolb)
• Косая сажень в плечах: A slanted sazhen in the shoulders – about a strong, wide-shouldered person
• Мерить всех на свой аршин: To gauge everybody by the same [literally: one's own] yardstick
• Проглотить аршин: To swallow an arshin (yardstick) – about standing very straight and still
• От горшка два вершка: Two vershok above the pot – a very young child
• Сто пудов: a hundred poods – a very large amount. In modern colloquial Russian it is used in a generic meanings of "very much" and "very", as well as "most surely".^[3] The adjective stopudovy and the adverb stopudovo derive from this expression, although it is more likely a mangled contraction of "100%" (stoprocentny).
• Семь пядей во лбу: Seven pyad across the forehead – very smart
• Не семь пядей во лбу: Not seven pyad across the forehead – not so smart
• Мал золотник, да до́рог: A zolotnik is small, but expensive: when quality rather than quantity is important
• Идти семимильными шагами: To walk in 7-mile steps – any kind of very fast progress, e.g., of improvement
• Узнать, почём фунт лиха: To learn how much a pound of likho costs – to experience something bad
• Ни пяди земли (не уступить): Do not give up (even) a pyad of land
• Съесть пуд соли (вместе с кем-либо): To eat a 'pood' of salt (with somebody) – to have a long common experience with somebody (with the implication "to know someone well")
