How to Convert Millimeters to Points
To convert millimeters to points, multiply the 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 length in points is equal to the 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 fraction and decimal calculator can convert millimeters and points, and it automatically converts the results to US customary, imperial, and SI metric values.
Millimeters and points are both units used to measure length. Keep reading to learn more about each unit.
How to Convert Millimeters to Fractional Inches (1/16″, 1/32″ & 1/64″)
Plain-language method for turning decimal inches into a standard tape-measure or machinist ruler fraction
Calculators give you a decimal number (such as 0.19685 in), but tape measures and woodworking rulers are marked in binary fractions of an inch—most commonly 1/16″ on carpenter tapes, 1/32″ on fine woodworking rules, and 1/64″ on machinist scales.
Here is the step-by-step worked example for converting 5 millimeters (mm) into fractional inches:
- Find the decimal inches result: Convert 5 mm to inches to get 0.19685 in.
- Separate the whole inches from the decimal part: Keep the whole number 0 aside, leaving the decimal remainder 0.19685.
- Multiply the decimal part by your desired fraction denominator (16, 32, or 64) and round half up: Multiply 0.19685 by 16, 32, or 64, then round to the nearest whole number (values ending in .5 round up).
- Reduce the fraction to lowest terms: If the rounded top number (numerator) is even, divide both top and bottom by 2 (or their Greatest Common Divisor) until the top number is odd, then combine with your whole inches.
What Is a Millimeter?
A millimeter is a metric unit of length equal to one-thousandth (1/1,000) of a meter or one-tenth (1/10) of a centimeter. By international definition, there are exactly 25.4 millimeters in one inch. [1]
The millimeter, or millimetre, is a standard SI metric unit of length. Millimeters can be abbreviated as mm; for example, 1 millimeter can be written as 1 mm.
In the metric system, "milli" is the prefix for thousandths, or 10⁻³. Millimeters are the default unit on mechanical engineering drawings and architectural blueprints worldwide.
Millimeters are commonly measured using metric steel rules, digital vernier calipers, depth gauges, and micrometers in CNC machining, 3D printing, automotive fasteners, and precision manufacturing.
What Is a Point?
A point is a unit of length equal to 0.000352778 meters (m), the base unit for length. Desktop publishing point equal to 1/72 of an international inch (0.35278 mm). [2]
The point is classified as a standard unit of length. Points can be abbreviated as pt; for example, 1 point can be written as 1 pt.
When working with points (pt) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, points (pt) are widely used across fine-tolerance laboratory, analytical, and micro-scale length measurements within international standard workflows, engineering documentation, and technical data sheets.
When converting 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.
