About Converting Millimeters to Points
Millimeter and Point both measure length. Millimeter is most often used for engineering drawings and manufacturing tolerances worldwide (including in the us).
Formula
points = millimeters × 2.83464566911
This factor comes from each unit's defined relationship to the category's base unit: 1 millimeter equals 0.001 base units, and 1 point equals 0.0003527777778 base units, so dividing one by the other gives the direct millimeter-to-point factor of 2.83464566911.
Simple example
1 mm × 2.834645669 = 2.834645669 pt
1 millimeter = 2.834645669 points.
Real-world example
10 mm × 2.834645669 = 28.34645669 pt
10 millimeters = 28.34645669 points.

Understanding the Millimeter
Millimeter (mm) measures distance. A millimeter is one-thousandth of a meter. It is classified as a SI derived (metric prefix) unit.
Where it's used: Standard small/precision length unit worldwide, including in US engineering and manufacturing
Uses of the Millimeter today
- Engineering drawings and manufacturing tolerances worldwide (including in the US)
- Rainfall measurement in most countries
- Small-scale everyday measurement (screen sizes, hardware)
History of the Millimeter
The millimeter follows from the meter via the 'milli-' SI prefix (10⁻³). It is notable as one of the few metric units in routine US technical/engineering use, since precision manufacturing and electronics are often specified in millimeters even in the US.
Historical origin. Millimeter was not the invention of a single named person; it developed through the process described above.
Understanding the Point (pt)
A desktop publishing point is 1/72 inch.
Millimeter — sources
- BIPM SI Brochure — SI prefixes — Defines 'milli-' as the prefix for 10⁻³.
