Land equivalent ratio. The FAO defines land equivalent ratio (LER) as: [2] the ratio of the area under sole cropping to the area under intercropping needed to give equal amounts of yield at the same management level. It is the sum of the fractions of the intercropped yields divided by the sole-crop yields.
We may need to convert land area units such as aana to dhur, dhur to aana, kattha to aana, ropani to bigha, square meter to aana, square meter to dhur etc, For such area units conversion you may use Area Converter Calculator. [3] The precise land measurement conversions as per Nepal standard are as follows:
Shoelace scheme for determining the area of a polygon with point coordinates (,),..., (,). The shoelace formula, also known as Gauss's area formula and the surveyor's formula, [1] is a mathematical algorithm to determine the area of a simple polygon whose vertices are described by their Cartesian coordinates in the plane.

Floor area ratio (FAR) is the ratio of a building's total floor area (gross floor area) to the size of the piece of land upon which it is built. It is often used as one of the regulations in city planning along with the building-to-land ratio. [ 1 ]
The bigha is a traditional unit of land in several parts of North & East India. Sale and purchase of land (particularly agricultural land) is still done unofficially in this unit. However, the area is recorded in hectare or square metres in official land records. Bigha varies in size from one part of India to another.
Since an acre measured 10 square chains in Gunter's system, the entire process of land area measurement could be computed using measurements in chains, and then converted to acres by dividing the results by 10. [2] Hence 10 chains by 10 chains (100 square chains) equals 10 acres, 5 chains by 5 chains (25 square chains) equals 2.5 acres.
The acre (/ ˈ eɪ k ər / AY-kər) is a unit of land area used in the British imperial and the United States customary systems. It is traditionally defined as the area of one chain by one furlong (66 by 660 feet ), which is exactly equal to 10 square chains, 1 ⁄ 640 of a square mile, 4,840 square yards, or 43,560 square feet, and ...
Katha or Biswa (also spelled kattha or cottah; Hindi: कट्ठा, Assamese: কঠা, Bengali: কাঠা) is a unit of area mostly used for land measurement in India, Nepal, and Bangladesh. After metrication in the mid-20th century by these countries, the unit became officially obsolete. But this unit is still in use in much of ...
