To convert points to furlongs, multiply by 1.753647587e-06. That factor is the whole relationship: both units measure length, so the conversion is a proportion with no offset and no substance-specific constant.
The DTP point: exactly 1/72 inch, the unit type size is set in. 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". Two tables follow: rounded steps for quick lookup, and a set of real reference quantities converted into furlongs, which is usually more useful than the bare number.

Worked examples
A credit card’s long edge: 243 pt in furlongs
At 243 pt (a credit card’s long edge), the same quantity in furlongs is 243 × 1.75365e-06 = 0.000426136 fur. One point is 1.75365e-06 furlongs, so the numbers shrink as expected.
An Olympic pool: 1.42e+05 pt in furlongs
At 1.42e+05 pt (an olympic pool), the same quantity in furlongs is 1.42e+05 × 1.75365e-06 = 0.249018 fur. One point is 1.75365e-06 furlongs, so the numbers shrink as expected.

Frequently asked questions
How many furlongs are in one point?
Exactly 1.75364758698e-06. 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 points to furlongs?
furlongs = points × 1.75364758698e-06. Reversed, points = furlongs ÷ 1.75364758698e-06, which is the same as multiplying by 570,240.
Which is the bigger unit, the point or the furlong?
The furlong. One point is only 1.75365e-06 of a furlong, so it takes 570,240 points 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 point?
The DTP point: exactly 1/72 inch, the unit type size is set in.
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.
Is there a quick way to do pt to fur in my head?
Plenty of people do this in their head: divide by 570,000 instead of using the exact factor 0.000002. At 100 that shortcut gives 0.0001754386 furlongs, off by 7.3838e-08 furlongs or about 0.04%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
