Why is the foot (US survey) unit used in land surveying?

Foot (US survey) has historically been applied for property boundaries and cadastral surveys primarily in the United States.

What makes the gigameter useful for astronomical distances?

The gigameter represents very large lengths, such as distances within the Solar System, making it ideal for planetary and interplanetary measurements.

Are foot to gigameter conversions practical for everyday measurements?

No, the vast difference in scale results in extremely small decimal values, which are generally impractical for common terrestrial use.
