Sazhens to Feet (sazhen to ft)

1 sazhen equals 7 feet exactly.

1 sazhen = 7 feet

How to convert sazhens to feet

To convert sazhens to feet, multiply the number of sazhens by 7. This factor is exact. To go the other way, multiply feet by 0.1428571429 (rounded).

feet = sazhens × 7

Example: 10 sazhens = 70 feet.

About these units

Sazhen (sazhen)

Russian (Imperial)Historical unit (no longer in standard use)

Exactly 7 feet (2.1336 m). The standard Russian fathom, defined by Peter the Great to match the English foot.

Russian builders, surveyors and rope makers measured with the sazhen, a word usually translated as fathom. In its Imperial form it was three arshins, or exactly seven English feet, giving the 2.1336 m used here. The English link comes from Peter the Great, who redefined the Russian units in terms of English inches and feet instead of replacing them.

Older and informal sazhens were looser. The swung sazhen was the span between the fingertips of outstretched arms, about 1.76 m, while the oblique sazhen, measured from a raised hand to the opposite foot, was 3.5 arshins or 2.4892 m. Land area was counted in square sazhens, and the treasury desyatina contained 2,400 of them.

Five hundred sazhens made a verst. Seven English feet is a convenient size to picture, since it is close to a tall doorway, and a sazhen equals about 2.13 m in metric terms.

1 sazhen = 2.1336 meters (exactly).

Foot (ft)

US & ImperialCurrent unit

12 inches. Defined as exactly 0.3048 meters. Still the standard unit for height, altitude in aviation and room dimensions in the US and UK.

Human anatomy supplied the idea: an adult foot is roughly 15 percent of body height. Ancient cultures turned that into standards, but not the same one. The Greek pous was about 302 mm, the standard Roman pes about 295.7 mm, and a Harappan foot of about 335 mm has been reported from the Indus Valley. Historically, a foot fell somewhere between about 250 and 335 mm. Charlemagne tried to standardize units around 790 with little lasting success, and in 1593 English law fixed the statute mile at 5,280 feet.

The modern foot dates from the 1959 International Yard and Pound Agreement, which defined the yard as exactly 0.9144 meter and so the foot as exactly 0.3048 meter; the UK adopted it on 1 January 1964. The US survey foot, defined in 1893 as 1200/3937 meter, was deprecated on 31 December 2022. Feet remain in everyday use for height and rooms in the US, and ISO shipping containers are defined in them. Aviation altitudes use them too: flight level 330 means 33,000 feet.

1 foot = 0.3048 meters (exactly).
