Gunter's chain (also known as Gunter's measurement) is a distance-measuring device used for surveying. It was designed and introduced in 1620 by English clergyman and mathematician Edmund Gunter (1581–1626). It enabled plots of land to be accurately surveyed and plotted, for legal and commercial purposes. Gunter developed an actual measuring ...
The chain (abbreviated ch) is a unit of length equal to 66 feet (22 yards ), used in both the US customary and Imperial unit systems. It is subdivided into 100 links. [ 1][ 2] There are 10 chains in a furlong, and 80 chains in one statute mile. [ 2] In metric terms, it is 20.1168 m long. [ 2] By extension, chainage (running distance) is the ...
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.
4 guntha = 1 jareeb = 484 square yard; 4 jareeb = 1 kanee = 1936 square yard; 10 jareeb = 1 acre = 4840 square yard; 25 acres = 1 marabba; See also. Conversion of units;
Power of 10. Visualisation of powers of 10 from one to 1 trillion. A power of 10 is any of the integer powers of the number ten; in other words, ten multiplied by itself a certain number of times (when the power is a positive integer). By definition, the number one is a power (the zeroth power) of ten. The first few non-negative powers of ten are:
In the metric system, the mass per unit area of all types of textiles is expressed in grams per square metre (g/m 2 ). The gram (alternative spelling: gramme; SI unit symbol: g) is a metric system unit of mass. A gram is defined as one thousandth of the SI base unit, the kilogram, or 1 × 10−3 kg.
For instance, 299 792 458 m/s (the speed of light in vacuum, in metres per second) can be written as 2.997 924 58 × 10 8 m/s and then approximated as 2.998 × 10 8 m/s. SI prefixes based on powers of 10 are also used to describe small or large quantities. For example, the prefix kilo means 10 3 = 1000, so a kilometre is 1000 m.
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.
