How to Convert Points to Nanometers
To convert points to nanometers, multiply the length by the following conversion ratio: 352,777.7777778 nanometers/point.
Since one point is equal to 352,777.7777778 nanometers, you can use this simple formula to convert:
The length in nanometers is equal to the length in points multiplied by 352,777.7777778.
For example, here's how to convert 5 points to nanometers using the formula above.
How Many Nanometers Are in a Point?
There are 352,777.7777778 nanometers in a point, which is why we use this value in the formula above.
Our point fraction and decimal calculator can convert points and nanometers, and it automatically converts the results to US customary, imperial, and SI metric values.
Points and nanometers are both units used to measure length. Keep reading to learn more about each unit.
How to Convert Points 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 0.069444 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 points (pt) into fractional inches:
- Find the decimal inches result: Convert 5 pt to inches to get 0.069444 in.
- Separate the whole inches from the decimal part: Keep the whole number 0 aside, leaving the decimal remainder 0.069444.
- Multiply the decimal part by your desired fraction denominator (16, 32, or 64) and round half up: Multiply 0.069444 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 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). [1]
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.
What Is a Nanometer?
One nanometer is equal to one-billionth (1/1,000,000,000) of a meter, which is defined as the distance light travels in a vacuum in a 1/299,792,458 second time interval. [2]
The nanometer, or nanometre, is a multiple of the meter, the SI base unit for length. In the metric system, "nano" is the prefix for billionths, or 10⁻⁹. Nanometers can be abbreviated as nm; for example, 1 nanometer can be written as 1 nm.
Because 1 inch equals 25.4 millimeters and 1 millimeter equals 1,000,000 nanometers, there are exactly 25,400,000 nanometers in 1 inch (and 10 Angstroms in 1 nanometer).
The nanometer is an extremely small unit of length measurement, often used to measure things that are very small, such as the wavelengths of visible light (400 nm to 700 nm), the transistors and electrical pathways in computer processors, and thin-film nanotechnology.
When converting length between points (pt) and nanometers (nm), keep full floating-point precision (1 pt = 352,777.7777778 nm; 1 nm = 0.000002835 pt) during intermediate calculations and round only the final nanometer figure to match your instrument tolerance.
