Area; system unit code (alternative) QID symbol or abbrev. notes sample default conversion combinations SI: square kilometre: km2 Q712226: km 2: US spelling: square kilometer 1.0 km 2 (0.39 sq mi)
There are several other common units for area. The are was the original unit of area in the metric system, with: 1 are = 100 square metres; Though the are has fallen out of use, the hectare is still commonly used to measure land: [13] 1 hectare = 100 ares = 10,000 square metres = 0.01 square kilometres; Other uncommon metric units of area ...
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:
Conversion of units is the conversion of the unit of measurement in which a quantity is expressed, typically through a multiplicative conversion factor that changes the unit without changing the quantity. This is also often loosely taken to include replacement of a quantity with a corresponding quantity that describes the same physical property.
An input unit can be converted to any number of output units—the outputs are specified as a "combination" by separating unit codes with a space (" ") or a plus ("+"). Using a space as a separator does not work if any of the unit codes contains a space.
The barn (b) is a unit of area used in nuclear physics equal to one hundred femtometres squared (100 fm 2 = 10 −28 m 2). The are (a) is a unit of area equal to 100 m 2. The decare (daa) is a unit of area equal to 1000 m 2. The hectare (ha) is a unit of area equal to 10 000 m 2 (0.01 km 2).
Conversions between units in the metric system are defined by their prefixes (for example, 1 kilogram = 1000 grams, 1 milligram = 0.001 grams) and are thus not listed in this article. Exceptions are made if the unit is commonly known by another name (for example, 1 micron = 10 −6 metre).
A barn (symbol: b) is a metric unit of area equal to 10 −28 m 2 (100 fm 2).Originally used in nuclear physics for expressing the cross sectional area of nuclei and nuclear reactions, today it is also used in all fields of high-energy physics to express the cross sections of any scattering process, and is best understood as a measure of the probability of interaction between small particles.
