The marla is a traditional unit of area that is used in India, Pakistan and Bangladesh. The marla was standardized under British raj to be equal to the square rod, or 272.25 square feet, 30.25 square yards, or 25.2929 square metres.
A commonly used land measurement unit in Punjab is karam or square karam. [3] Other units include the Sarsai and units listed. [4] This the current system of measurement of farm land. All Units. 1 karam × 1 karam = 1 sq. karam 5.5 feet × 5.5 feet = 30.25 sq. feet 30.25 square feet = 1 Sarsai 9 Sarsai (sq. Karam) = 1 Marla (272.25 sq. feet)
One acre equals 1 ⁄ 640 (0.0015625) square mile, 4,840 square yards, 43,560 square feet, [2] or about 4,047 square metres (0.4047 hectares) (see below).While all modern variants of the acre contain 4,840 square yards, there are alternative definitions of a yard, so the exact size of an acre depends upon the particular yard on which it is based.
Geographical distance or geodetic distance is the distance measured along the surface of the Earth, or the shortest arch length. The formulae in this article calculate distances between points which are defined by geographical coordinates in terms of latitude and longitude. This distance is an element in solving the second (inverse) geodetic ...

The metric system of measurement was first given a legal basis in 1795 by the French Revolutionary government. The law of 18 Germinal, Year III (7 April 1795) defined five units of measure: [18] The metre for length; The are (100 m 2) for area [of land] The stère (1 m 3) for volume of stacked firewood [19] The litre (1 dm 3) for volumes of liquid
The basic unit of length in the imperial and U.S. customary systems is the yard, defined as exactly 0.9144 m by international treaty in 1959. [ 2 ] [ 5 ] Common imperial units and U.S. customary units of length include: [ 6 ]
For example, in classical mechanics the coefficient of friction is commonly used to measure the roughness of a surface as it relates to the force exerted on another contacted object. And, in fluid dynamics, hydraulic roughness is a measure of the resistance water experiences when flowing over land or through a channel. All of these measures ...
