What is a furlong (US survey)?

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

What is a light year?

A light year is a unit of length equal to the distance light travels in a vacuum in one Julian year, approximately 9.4607 × 10^15 meters.

Why convert furlongs to light years?

Converting furlongs to light years helps relate terrestrial land distances to astronomical scales, useful in education and interdisciplinary studies.
