### What are Barn and Square Kilometer

Definition of Barn

A barn is a unit of area measurement used in nuclear physics to quantify the effective cross-sectional area of atomic nuclei and scattering events. Its symbol is 'b', and it is equivalent to 10^-28 square meters. The term 'barn' evokes the phrase 'as big as a barn,' humorously representing the likelihood of nuclear particle interactions; despite being a small unit, it's relatively 'large' in the nuclear realm.

Definition of Square Kilometer

A square kilometer (symbol: km^2) is a metric unit of area that is equal to one million square meters. It is typically used to measure the area of geographical regions such as towns, cities, and countries. One square kilometer is a substantial area, often used to represent the size of urban environments and natural landscapes on a macroscopic scale.

### Barn to Square Kilometer Conversion Table

Barn (b) Square Kilometer (km^2)
1 b 1e-28 km^2
10 b 1e-27 km^2
100 b 1e-26 km^2
1,000 b 1e-25 km^2
10,000 b 1e-24 km^2
100,000 b 1e-23 km^2
1 million b 1e-22 km^2
10 million b 1e-21 km^2
100 million b 1e-20 km^2
1 billion b 1e-19 km^2

#### Conversion of Barn to Square Kilometer

1 b = 1e-28 km^2

Example 1:
Convert 50 b to km^2:
50 b = 50 × 1e-28 km^2 = 5e-27 km^2

Example 2:
Convert 250 b to km^2:
250 b = 250 × 1e-28 km^2 = 2.5e-26 km^2

### History of Barn and Square Kilometer

Despite its playful name, the 'barn' became an official unit in nuclear physics around the 1940s. Originating from the Manhattan Project, scientists used this term as a measure of cross-sectional area in nuclear reactions. The barn allows for easier discussion of very small areas, a convenience that is now translated into various other measurements, such as square kilometers for larger-scale applications.
