Point vs Micrometre: which is bigger?
A point is the larger unit: one point equals 352.7778 micrometres. Put another way, you need 352.7778 micrometres to make a single point.
What is a Point? History, origin and usage
The typographic point grew out of 18th-century European type systems; Francois-Ambroise Didot refined it in 1783 to one-seventy-second of a Paris inch. American typefounders standardised their own point in 1886, and in the late 1980s the desktop-publishing (PostScript) point, defined as exactly 1/72 of an inch, became the digital standard when Adobe and Apple adopted it.
The point is the unit used to specify font sizes and line spacing in typography and word processors worldwide. Twelve points make one pica, and six picas make one inch.
The '12-point font' on your screen descends directly from the type sizes cast in metal by 19th-century printers. The European Didot point and the modern DTP point differ slightly, so the same point size can render differently in older continental typography.
What is a Micrometre? History, origin and usage
The micrometre, one-millionth of a metre, was long called the 'micron', a name officially adopted by the international metrology body in 1879. In 1967 the SI formally replaced 'micron' with 'micrometre' so the standard micro- prefix (symbol µ) would be used consistently.
The micrometre measures things invisible to the naked eye: biological cells, bacteria, fibres and the wavelengths of infrared light. It is also common in optics and in fibre-optic and semiconductor engineering.
A human hair is roughly 50 to 100 micrometres across. Despite being officially deprecated, 'micron' survives in everyday industrial use, partly to avoid confusion with the micrometer measuring instrument.

Tips for converting Point to Micrometre
- To go from point to micrometre, multiply by 352.7778; to go back, divide by 352.7778 (or multiply by 0.002834646).
- For a quick mental estimate, remember that 1 point ≈ 352.7778 micrometre, so 10 point ≈ 3,527.778 micrometre.
- The converter above keeps full precision; the tables round for readability, so use the tool for exact figures.
- Both fields update live as you type — change either side to convert in that direction.
How to use this Point to Micrometre converter
Type a number into the Point field and the equivalent in Micrometre appears instantly — there is no “convert” button to press and nothing is sent to a server, so it works offline once the page has loaded and is safe for any data. You can also type into the Micrometre field to convert the other way (micrometre to point). Use the swap control to flip the two units, and copy the result with a single click. Because the calculation runs in your browser with full floating-point precision, the converter is more exact than the rounded figures shown in the reference chart above — use the chart for quick look-ups and the tool for precise work.
Accuracy and method
Every figure on this page — the formula, the worked examples, the conversion chart and the “convert to other units” tables — is computed from a single verified conversion factor (1 pt = 352.7778 µm), never copied from a hand-typed lookup table that could drift. That factor is derived from each unit’s definition in terms of a common base unit, and an automated check re-verifies all of the site’s factors on every update, so the numbers here stay correct over time. This matters for point-to-micrometre conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
Sources
- BIPM — The International System of Units (SI Brochure) — the defining document for the SI, published by the International Bureau of Weights and Measures. It fixes the base unit that this conversion resolves to, which is why the factor here can be exact rather than approximate.
- NIST — Definitions of the SI base units — the US National Institute of Standards and Technology reference for the SI base units, used here as an independent cross-check on the base-unit definition.
The metric units (km, m, cm, mm, µm) are exact by definition, and the imperial units (mile, yard, foot, inch, nautical mile) use their exact international values. Traditional units (hand, span, finger, cubit, rod/pole, link, rope, ken, league) are given at their commonly accepted standard sizes — historical local values sometimes differed, so confirm against a primary source before relying on them for legal or historical work.
