## What is square kilometers calculator?

The square kilometer calculator measures an area in kilometers so it’s called the square kilometers area. This sq km calculator is used to determine the area of rectangles. If a shape has an area of one square kilometer, it can be said to be a 1 sq km area.

## Square Kilometers Formula

The formula for calculating the square kilometers is

**SKM = L * W**

- SM = Square Kilometers
- L = Length of a rectangle in kilometers
- W = Width of a rectangle in kilometers

Square kilometer = length(kilometer) x width(kilometer)

If you calculate the total cost area then use this formula:-

Total cost Area = Area in Square kilometer * Price per square kilometers

## How do you calculate square kilometers?

Measure the length in kilometers and breadth in kilometers then multiply the length and breadth but if the length and breadth are not in km then first convert in kilometers and then multiply.

## Km to square km table.

kilometers | Square kilometers (km²) |
---|---|

1 km | 1*1 = 1 km² |

10 km | 10*10 = 100 km² |

20 km | 20*20 = 400 km² |

30 km | 30*30 = 900 km² |

40 km | 40 *40 = 1600 km² |

50 km | 50*50 = 2500 km² |

60 km | 60*60 = 3600 km² |

70 km | 70*70 = 4900 km² |

80 km | 80*80 = 6400 km² |

90 km | 90*90 = 8100 km² |

100 km | 100*100 = 10000 km² |
