  2. Rod (unit) - Wikipedia

    en.wikipedia.org/wiki/Rod_(unit)

    The rod is useful as a unit of length because integer multiples of it can form one acre of square measure (area). The 'perfect acre' [2] is a rectangular area of 43,560 square feet, bounded by sides 660 feet (a furlong) long and 66 feet (a chain) wide (220 yards by 22 yards) or, equivalently, 40 rods by 4 rods. An acre is therefore 160 square ...

    en.wikipedia.org/wiki/Rood_(unit)

    Rood is an English unit of area equal to one quarter of an acre [2] or 10,890 square feet, exactly 1,011.7141056 m 2. A rectangle that is one furlong (i.e., 10 chains, or 40 rods) in length and one rod in width is one rood in area, as is any space comprising 40 perches (a perch being one square rod). The vergée was also a quarter of a Normandy ...

    [25] [26] The standard FIFA football pitch for international matches is 105 m (344 ft) long by 68 m (223 ft) wide (7,140 m 2 or 0.714 ha or 1.76 acres); FIFA allows for a variance of up to 5 m (16.4 ft) in length in either direction and 7 m (23.0 ft) more or 4 m (13.1 ft) less in width (and larger departures if the pitch is not used for ...

    At each 5-yard line they are marked with 2-foot (0.61 m) lines painted parallel to the sidelines. Between the 5-yard lines they are marked with 2-foot lines painted perpendicular to the sidelines at 1-yard intervals. The hash marks are painted so that the edge farthest from the sideline is the required distance from the sideline.

    en.wikipedia.org/wiki/Katha_(unit)

    One Katha is equal to 1,361.25 ft 2 or 151.25 square yard or 126.46 square metre. One Bigha in UP can range from 5 to 20 Katha. In Western UP, 1 Bigha can be 5.0 Katha (756.25 square yard) or 6.6667 Katha (1,008.33 square yard). In Eastern UP, 1 Bigha is 20 Katha (3,025 square yard). 1 Katha or 1 Biswa = 20 Dhur or 20 Biswansi; 1 Dhur = 1 Biswansi

  7. Area - Wikipedia

    en.wikipedia.org/wiki/Area

    Calculation of the area of a square whose length and width are 1 metre would be: 1 metre × 1 metre = 1 m 2. and so, a rectangle with different sides (say length of 3 metres and width of 2 metres) would have an area in square units that can be calculated as: 3 metres × 2 metres = 6 m 2. This is equivalent to 6 million square millimetres.

  8. League (unit) - Wikipedia

    en.wikipedia.org/wiki/League_(unit)

    Legua nautica (nautical league): Between 1400 and 1600 the Spanish nautical league was equal to four Roman miles of 4,842 feet, making it 19,368 feet (5,903 metres or 3.1876 modern nautical miles). However, the accepted number of Spanish nautical leagues to a degree varied between 14 1/6 to 16 2/3, so in actual practice the length of a Spanish ...

  9. Equable shape - Wikipedia

    en.wikipedia.org/wiki/Equable_shape

    An area cannot be equal to a length except relative to a particular unit of measurement. For example, if shape has an area of 5 square yards and a perimeter of 5 yards, then it has an area of 45 square feet (4.2 m 2) and a perimeter of 15 feet (since 3 feet = 1 yard and hence 9 square feet = 1 square yard). Moreover, contrary to what the name ...
