What is a furlong (US survey)?

A furlong (US survey) is a historic length unit used in U.S. land surveying, equal to 660 US survey feet or about 201.1684 meters.

What distances are measured in gigameters?

Gigameters express very large distances such as those within the Solar System, spacecraft trajectories, and separations between planets.

Can I use this converter for modern land surveying?

No, because furlong (US survey) is a historic unit, and gigameters are suited for astronomical scales, making the converter unsuitable for modern terrestrial measurements.
