In Assam, a bigha is 14,400 square feet (1,340 m 2) or 1,600 sq yard.One bigha is divided into 5 Katha. [2] [3] Each Katha consists of 20 Lessa.Hence each Katha is 2,880 square feet (268 m 2) in area, although this may vary within different regions of Assam. 4 bighas together are further termed as a Pura.
In Bangladesh, one katha is standardized to 720 square feet (67 m 2), and 20 katha equals 1 bigha. 1 Katha (কাঠা) = 720 sq. feet = 66.88 sq. metre = 1.652 Decimal (শতাংশ/ শতক) 1 Bigha (বিঘা) = 20 Katha (কাঠা) = 14,400 square feet = 1,338 sq m = 1,600 sq yard
Comparison of 1 square metre with some Imperial and metric units of area. The square metre (international spelling as used by the International Bureau of Weights and Measures) or square meter (American spelling) is the unit of area in the International System of Units (SI) with symbol m 2. [1]
Comparison of 1 square foot with some Imperial and metric units of area. The square foot (pl. square feet; abbreviated sq ft, sf, or ft 2; also denoted by ' 2 and ⏍) is an imperial unit and U.S. customary unit (non-SI, non-metric) of area, used mainly in the United States, Canada, the United Kingdom, Bangladesh, India, Nepal, Pakistan, Ghana, Liberia, Malaysia, Myanmar, Singapore and Hong Kong.
1 acre = 4,840 square yards = 43,560 square feet. An acre is approximately 40% of a hectare. On the atomic scale, area is measured in units of barns, such that: [13] 1 barn = 10 −28 square meters. The barn is commonly used in describing the cross-sectional area of interaction in nuclear physics. [13]
The square is an Imperial unit of area that is used in the construction industry in the United States and Canada, [1] and was historically used in Australia. One square is equal to 100 square feet . Examples where the unit is used are roofing shingles, metal roofing, vinyl siding, and fibercement siding products.
In the cases where non-SI units are used, the numerical calculation of a formula can be done by first working out the factor, and then plug in the numerical values of the given/known quantities. For example, in the study of Bose–Einstein condensate , [ 6 ] atomic mass m is usually given in daltons , instead of kilograms , and chemical ...
The square of an integer may also be called a square number or a perfect square. In algebra, the operation of squaring is often generalized to polynomials, other expressions, or values in systems of mathematical values other than the numbers. For instance, the square of the linear polynomial x + 1 is the quadratic polynomial (x + 1) 2 = x 2 ...
