To convert microns to points, multiply by 0.002834645669. 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. The older name for a micrometre, still standard in filtration, machining and paint-thickness specifications.
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". The tables underneath give both a plain step-by-step lookup and a list of real quantities expressed in points, so you can sanity-check whether your answer is a plausible size.

Worked examples
A door height: 2.03e+06 micron in points
At 2.03e+06 micron (a door height), the same quantity in points is 2.03e+06 × 0.00283465 = 5754.33 pt. One micron is 0.00283465 points, so the numbers shrink as expected.
A credit card’s long edge: 8.56e+04 micron in points
At 8.56e+04 micron (a credit card’s long edge), the same quantity in points is 8.56e+04 × 0.00283465 = 242.646 pt. One micron is 0.00283465 points, so the numbers shrink as expected.
How to read your score
Frequently asked questions
How many points are in one micron?
Exactly 0.00283464566929. 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 microns to points?
points = microns × 0.00283464566929. Reversed, microns = points ÷ 0.00283464566929, which is the same as multiplying by 352.777777778.
Which is the bigger unit, the micron or the point?
The point. One micron is only 0.00283465 of a point, so it takes 352.778 microns to make one point.
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 micron?
The older name for a micrometre, still standard in filtration, machining and paint-thickness specifications.
What is a point?
The DTP point: exactly 1/72 inch, the unit type size is set 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 micron to pt in my head?
Plenty of people do this in their head: divide by 350 instead of using the exact factor 0.002834645669. At 100 that shortcut gives 0.28571429 points, off by 0.00225 points or about 0.79%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
