How to Convert Millimeters to Points
To convert millimeters to points, multiply the typographical length by the following conversion ratio: 2.8346457 points/millimeter.
Since one millimeter is equal to 2.8346457 points, you can use this simple formula to convert:
The typographical length in points is equal to the typographical length in millimeters multiplied by 2.8346457.
For example, here's how to convert 5 millimeters to points using the formula above.
How Many Points Are in a Millimeter?
There are 2.8346457 points in a millimeter, which is why we use this value in the formula above.
Our millimeter to point calculator automatically converts your typographical length measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Millimeters and points are both units used to measure typographical length. Keep reading to learn more about each unit.
What Is a Millimeter?
A millimeter is a unit of typographical length equal to 2.8346457 points (pt), the base unit for typographical length. 1 mm = 2.83464567 DTP points. [1]
The millimeter is classified as a metric and SI-compatible unit of typographical length. Millimeters can be abbreviated as mm; for example, 1 millimeter can be written as 1 mm.
In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the millimeter (mm) a convenient decimal multiple of the point (pt).
In practice, millimeters (mm) are widely used across standard typographical length applications within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Point?
Standard Desktop Publishing point equal to 1/72 of an international inch (0.352778 mm). It serves as a primary reference unit for measuring typographical length across scientific and practical applications. [2]
The point is classified as a standard unit of typographical length. Points can be abbreviated as pt; for example, 1 point can be written as 1 pt.
As the primary coherent reference unit for typographical length in this category, all other typographical length units are mathematically anchored to the point (pt).
In practice, points (pt) are widely used across standard typographical length applications within international standard workflows, engineering documentation, and technical data sheets.
When converting typographical length between millimeters (mm) and points (pt), keep full floating-point precision (1 mm = 2.8346457 pt; 1 pt = 0.3527778 mm) during intermediate calculations and round only the final point figure to match your instrument tolerance.
