Unit definitions

Square kilometer

The square kilometer is the area of a square with sides measuring $1$ kilometer. A square kilometer is equal to $1\,000\,000$ square meters ($10^6\ \text{m}^2$).

Square meter

The square meter is the SI unit of area. It is the area of a square with sides measuring $1$ meter.

How to convert Square kilometer to Square meter

$$\text{Area}_{\text{m²}} = \text{Area}_{\text{km²}} \cdot 1000000$$

Examples

Example 1

Convert $40.0\ \text{km²}$ to $\text{m²}$.

$$\text{Area}_{\text{m²}} = 40.0 \cdot 1000000$$

$$\text{Area}_{\text{m²}} = 40000000$$

$$\therefore \ 40.0\ \text{km²} = 40000000 \ \text{m²}$$

Example 2

Convert $90.0\ \text{km²}$ to $\text{m²}$.

$$\text{Area}_{\text{m²}} = 90.0 \cdot 1000000$$

$$\text{Area}_{\text{m²}} = 90000000$$

$$\therefore \ 90.0\ \text{km²} = 90000000 \ \text{m²}$$

Example 3

Convert $100.0\ \text{km²}$ to $\text{m²}$.

$$\text{Area}_{\text{m²}} = 100.0 \cdot 1000000$$

$$\text{Area}_{\text{m²}} = 100000000$$

$$\therefore \ 100.0\ \text{km²} = 100000000 \ \text{m²}$$

Example 4

Convert $135.0\ \text{km²}$ to $\text{m²}$.

$$\text{Area}_{\text{m²}} = 135.0 \cdot 1000000$$

$$\text{Area}_{\text{m²}} = 135000000$$

$$\therefore \ 135.0\ \text{km²} = 135000000 \ \text{m²}$$

Example 5

Convert $190.0\ \text{km²}$ to $\text{m²}$.

$$\text{Area}_{\text{m²}} = 190.0 \cdot 1000000$$

$$\text{Area}_{\text{m²}} = 190000000$$

$$\therefore \ 190.0\ \text{km²} = 190000000 \ \text{m²}$$
