What is a foot (US survey)?

The US survey foot is a unit of length used historically in land surveying in the United States, defined exactly as 1200/3937 meters.

What does Earth's distance from the Sun represent in this converter?

It represents the astronomical unit, which is the average distance between Earth and the Sun, used for measuring solar system distances.

Why is the conversion factor so small?

Because Earth's distance from the Sun is extremely large compared to a foot, the conversion factor is a very small number reflecting the scale difference.
