How to Convert Inches to Nanometers

To convert a measurement in inches to a measurement in nanometers, multiply the length by the following conversion ratio: 25,400,000 nanometers/inch.

Since one inch is equal to 25,400,000 nanometers, you can use this simple formula to convert:

nanometers = inches × 25,400,000

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

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

How Many Nanometers Are in an Inch?

There are 25,400,000 nanometers in an inch, which is why we use this value in the formula above.

1" = 25,400,000 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.

What Is an Inch?

An inch is a unit of length 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 known as a double-prime. Often a double-quote (") is used instead of a double-prime for convenience. A double-prime is commonly used to express 1 in as 1″.

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

The standard ruler is 12 inches long and is a common tool for measuring a length in inches. Another frequently used tool to perform measurements in inches is a tape measure, which commonly comes in lengths from 6' - 35'. Other types of devices used to make measurements in inches include scales, calipers, measuring wheels, micrometers, yardsticks, and even lasers.

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.

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 billionths, or 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 a combination of both values, so make sure you get the correct type for your needs.
