The **Square Kilometer** is a unit of surface measure, which corresponds to the area of a square with a kilometer of side. This measure is equivalent to one million square meters, or even to one hundred hectares. In many of the medieval cities of Europe, the area that was protected by the walls that surrounded the city, was about one square kilometer. With an area of 59.1 km², Manhattan has a population of 1,640,000. This gives an average of 27,750 people/km², which makes it one of the most densely populated areas on the planet!

One **Hectare** equals to one square hectometer or one hundred ares. This in square meters results in 10,000 m². To get the idea of what represents one hectare, just imagine a square terrain, with one hundred meters on each side. If you are a football fan, you can use the measure of the area of the playing field as equivalent to about one hectare. This is essentially an agrarian measure, widely used in calculating the size of agricultural areas, forests and natural areas. For example, at the time of fires, the burning area is always expressed in hectares.

`ha=km^2 xx 100`

If you do not wish to use our converter, you can always choose to perform the mathematical conversion operations manually. To do this, simply follow the following steps:

- Replace the variable
**km²**with the value in km2 that you want to convert. - Carry out mathematical operations, respecting priorities.
- Get the final value of hectare with the rounding you want.

km2 to hectare | km2 to hectare |
---|---|

0.5 km² = 50 ha | 30 km² = 3000 ha |

1 km² = 100 ha | 35 km² = 3500 ha |

2 km² = 200 ha | 40 km² = 4000 ha |

3 km² = 300 ha | 45 km² = 4500 ha |

4 km² = 400 ha | 50 km² = 5000 ha |

5 km² = 500 ha | 60 km² = 6000 ha |

10 km² = 1000 ha | 70 km² = 7000 ha |

15 km² = 1500 ha | 80 km² = 8000 ha |

20 km² = 2000 ha | 90 km² = 9000 ha |

25 km² = 2500 ha | 100 km² = 10000 ha |
