How to Convert Inches to Nanometers

Tape measures can be used to measure units of length, and a calculator can be used to convert to another unit

To convert an inch measurement to a nanometer measurement, multiply the length by the conversion ratio. One inch is equal to 25,400,000 nanometers, so use this simple formula to convert:

nanometers = inches × 25,400,000

The length in nanometers is equal to the inches multiplied by 25,400,000.

For example, here's how to convert 5 inches to nanometers using the formula above.
5" = (5 × 25,400,000) = 127,000,000 nm

Our inch fraction calculator can add inches and nanometers together and it also automatically converts the results to US customary, imperial and SI metric values.

Inches and nanometers are both units used to measure length. Keep reading to learn more about each unit of measure.


An inch is a unit of linear length measure equal to 1/12 of a foot or 1/36 of a yard. Because the international yard is legally defined to be equal to exactly 0.9144 meters, one inch is equal to 2.54 centimeters.[1]

The inch is a US customary and imperial unit of length. Inches can be abbreviated as in, for example 1 inch can be written as 1 in.

Inches can also be denoted using the symbol, otherwise know as a double-prime. Often a double-quote (") is used instead of a double-prime for convenience. Using the double-prime, 1 in can be written as 1″.

A quarter is .955" in diameter, which is just smaller than 1"

The standard ruler has 12", and are a common measuring tool for measuring inches. They are also often measured using tape measures which commonly come in lengths from 6' - 35'. Other types of measuring devices include scales, calipers, measuring wheels, micrometers, yardsticks, and even lasers.


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.

The nanometer, or nanometre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "nano" is the prefix for 10-9. Nanometers can be abbreviated as nm, for example 1 nanometer can be written as 1 nm.

The nanometer is an extremely small unit of length measurement, often used to measure things that are very small, such as the transistors and electrical pathways in computer processors and nanotechnology.

We recommend using a ruler or tape measure for measuring length, which can be found at a local retailer or home center. Rulers are available in imperial, metric, or combination with both values, so make sure you get the correct type for your needs.

If you need a ruler you can also download and print our free printable rulers, which include both imperial and metric measurements.
