How to Convert Twips to Millimeters
To convert twips to millimeters, multiply the typographical length by the following conversion ratio: 0.0176389 millimeters/twip.
Since one twip is equal to 0.0176389 millimeters, you can use this simple formula to convert:
The typographical length in millimeters is equal to the typographical length in twips multiplied by 0.0176389.
For example, here's how to convert 5 twips to millimeters using the formula above.
How Many Millimeters Are in a Twip?
There are 0.0176389 millimeters in a twip, which is why we use this value in the formula above.
Our twip to millimeter calculator automatically converts your typographical length measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Twips and millimeters are both units used to measure typographical length. Keep reading to learn more about each unit.
What Is a Twip?
A twip is a unit of typographical length equal to 1/20 of a point (0.05 pt). Twentieth of a point (1/1440 of an inch). [1]
The twip is classified as a standard unit of typographical length. Twips can be abbreviated as twip; for example, 1 twip can be written as 1 twip.
When working with twips (twip) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, twips (twip) are widely used across standard typographical length applications within international standard workflows, engineering documentation, and technical data sheets.
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. [2]
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.
When converting typographical length between twips (twip) and millimeters (mm), keep full floating-point precision (1 twip = 0.0176389 mm; 1 mm = 56.6929134 twip) during intermediate calculations and round only the final millimeter figure to match your instrument tolerance.
