Our millimeter to twip calculator automatically converts your typographical length measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Millimeters and twips 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 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). [2]
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.
When converting typographical length between millimeters (mm) and twips (twip), keep full floating-point precision (1 mm = 56.6929134 twip; 1 twip = 0.0176389 mm) during intermediate calculations and round only the final twip figure to match your instrument tolerance.
