What is a furlong (US survey)?

A furlong (US survey) is a historical non-SI unit of length used primarily in U.S. land surveying, defined as exactly 660 US survey feet or about 201.1684 meters.

What does the attometer measure?

An attometer is an SI unit representing extremely small lengths equal to one quintillionth of a meter, used in subnuclear and high-energy physics.

Why convert from furlongs to attometers?

Converting furlongs to attometers allows translation from large, traditional surveying units to extremely precise SI units, facilitating analysis across very different length scales.
