This page converts nanometers into furlongs using the factor 4.970969538e-12, and shows the reverse figure alongside it. Both units measure length, which is why one number does the whole job.
One billionth of a metre — the scale of light wavelengths and chip lithography. Ten chains, one eighth of a mile — the unit horse racing is still measured and bet in.
The mil and the millimetre are not the same thing and are out by a factor of about forty. A mil is one thousandth of an inch — 0.0254 mm — and a spec sheet that quotes film thickness in mils means the small unit. British drawings write the same size as "thou". Below the calculator there is a step table for the values people look up most, and a second table putting real length figures into furlongs so the number you get has something to be compared against.

Worked examples
A round figure: 1 nm in furlongs
At 1 nm (a round figure), the same quantity in furlongs is 1 × 4.97097e-12 = 4.97097e-12 fur. One nanometer is 4.97097e-12 furlongs, so the numbers shrink as expected.
A larger figure: 100 nm in furlongs
Take a larger figure, roughly 100 nm. The conversion is a single multiplication — 100 × 4.97097e-12 — giving 4.97097e-10 fur. Because the relationship is proportional, doubling the input doubles the answer to 9.94194e-10 fur.

Frequently asked questions
How many furlongs are in one nanometer?
Exactly 4.97096953790e-12. Every figure on this page is that one number multiplied by your input, so the only rounding is at the display step.
What is the formula to convert nanometers to furlongs?
furlongs = nanometers × 4.97096953790e-12. Reversed, nanometers = furlongs ÷ 4.97096953790e-12, which is the same as multiplying by 201,168,000,000.
Which is the bigger unit, the nanometer or the furlong?
The furlong. One nanometer is only 4.97097e-12 of a furlong, so it takes 2.01168e+11 nanometers to make one furlong.
What does this quantity actually measure?
Both units measure length. That is why a single factor is enough: there is no temperature offset and no material property involved, unlike conversions that cross between different quantities.
What is a nanometer?
One billionth of a metre — the scale of light wavelengths and chip lithography.
What is a furlong?
Ten chains, one eighth of a mile — the unit horse racing is still measured and bet in.
Why does my answer differ from another converter?
Almost always because the other tool rounded the factor before multiplying. This page keeps full double precision through the calculation and rounds only for display, and it prints the factor it used so you can see where any difference came from.
