## Square Meter and Square Kilometer

A square meter (m²) and a square kilometer (km²) are both units of area in the metric system. They are used to measure the size of a two-dimensional object or surface, such as a plot of land or the floor of a room.

### Square meter

A square meter is defined as the area of a square with sides of 1 meter. It is a standard unit of measurement in the metric system, and it is often used in everyday situations, such as when measuring the size of a room or a garden.

### Square Kilometer

A square kilometer, on the other hand, is a unit that is much larger than a square meter. It is defined as the area of a square with sides of 1 kilometer. A square kilometer is equal to 1,000,000 square meters. This unit is often used in geographical measurements and agricultural planning.

### Conversion factor

The relationship between square meter and square kilometer is linear and can be expressed as 1 km² = 1,000,000 m². This means that if you have the number of square meters, you can divide this number by 1,000,000 to get the number of square kilometers.

`1 km² = 1,000,000 m²`

Conversely, if you have the number of square kilometers, you multiply this number by 1,000,000 to get the number of square meters.

`1 m² = 0,000001 km²`

This conversion is particularly useful in surveying and geography, where large tracts of land are often measured in square kilometers, but smaller pieces of land and buildings are measured in square meters. Being able to convert between these units can assist in making accurate measurements and calculations.
