To convert square meters (m²) to hectares (ha), you can use the conversion factor:

1 hectare = 10,000 m²

To convert 693,000 m² to hectares:

\[
\text{hectares} = \frac{693,000 \, \text{m²}}{10,000 \, \text{m²/ha}}
\]

\[
\text{hectares} = 69.3 \, \text{ha}
\]

So, 693,000 m² is equal to 69.3 hectares.
