Convert Point to Millimetre

Quick answer: Point to Millimetre

1 Point = 0.3527778 Millimetre (pt → mm). To convert point to millimetre, multiply by 0.3527778. To convert millimetre to point, multiply by 2.834646. The converter at the top does this instantly and both ways; the sections below give the formula, worked examples, a full conversion chart and answers to the most common point-to-millimetre questions.

How to convert Point to Millimetre

To convert point to millimetre, multiply the number of point by the conversion factor 0.3527778, because 1 pt = 0.3527778 mm. The conversion is linear, so the same factor works for any value — whole numbers, decimals or fractions. For the reverse direction, 1 mm = 2.834646 pt, so you divide by 0.3527778 (or multiply by 2.834646) to turn millimetre back into point.

mm = pt × 0.3527778  ·  pt = mm × 2.834646

1. Write down the value you want to convert, in point.
2. Multiply it by 0.3527778.
3. The result is the same area/length/quantity expressed in millimetre.

Point to Millimetre conversion chart (both directions)

The chart below converts point to millimetre and millimetre to point side by side, so it works whichever way you need. 1 point = 0.3527778 millimetre, and 1 millimetre = 2.834646 point.

Point vs Millimetre: which is bigger?

A millimetre is the larger unit: one millimetre equals 2.834646 points. Put another way, you need 2.834646 points to make a single millimetre.

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 Millimetre? History, origin and usage

The millimetre is one-thousandth of a metre, taking its prefix from the Latin mille, 'thousand'. Like the other metric submultiples it dates to the French metric reform of the 1790s.

The millimetre is the workhorse of engineering drawings, machining and manufacturing, where tolerances are specified in millimetres or fractions of them. It is also the standard unit for rainfall and snowfall depth in meteorology.

Rainfall reported in 'millimetres' is the depth water would reach on a flat surface, so one millimetre of rain equals one litre per square metre. The smallest markings on most metric rulers are millimetres.

Tips for converting Point to Millimetre

• To go from point to millimetre, multiply by 0.3527778; to go back, divide by 0.3527778 (or multiply by 2.834646).
• For a quick mental estimate, remember that 1 point ≈ 0.3527778 millimetre, so 10 point ≈ 3.527778 millimetre.
• 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 Millimetre converter

Type a number into the Point field and the equivalent in Millimetre 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 Millimetre field to convert the other way (millimetre 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 = 0.3527778 mm), 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-millimetre conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.

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.

Frequently asked questions

How many millimetre are in 1 point?

1 point = 0.3527778 millimetre (mm). To convert any number of point to millimetre, multiply by 0.3527778.
