What is a furlong (US survey)?

It is a historical, non-SI length unit used in U.S. surveying, defined as 660 US survey feet or about 201.1684 metres.

What does the fermi measure?

The fermi is a unit equal to one femtometre (1×10⁻¹⁵ metres), used to express nuclear-scale distances.

Why convert furlongs to fermis?

Such conversion assists in linking historical land measurements to atomic-scale lengths, useful in educational or scientific contexts.
