How to Convert Feet to Nanometers

To convert a foot measurement to a nanometer measurement, multiply the length by the conversion ratio.

Since one foot is equal to 304,800,000 nanometers, you can use this simple formula to convert:

nanometers = feet × 304,800,000

The length in nanometers is equal to the feet multiplied by 304,800,000.

For example, here's how to convert 5 feet to nanometers using the formula above.
5' = (5 × 304,800,000) = 1,524,000,000 nm

How Many Nanometers Are in a Foot?

There are 304,800,000 nanometers in a foot, which is why we use this value in the formula above.

1' = 304,800,000 nm

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

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


The foot is a unit of linear length measure equal to 12 inches or 1/3 of a yard. Because the international yard is legally defined to be equal to exactly 0.9144 meters, one foot is equal to 0.3048 meters.[1]

The foot is a US customary and imperial unit of length. Feet can be abbreviated as ft; for example, 1 foot can be written as 1 ft.

Feet can also be denoted using the symbol, otherwise known as a prime, though a single-quote (') is often used instead of the prime symbol for convenience. Using the prime symbol, 1 ft can be written as 1′.

The foot is most commonly measured using either a standard 12" ruler or a tape measure, though there are many other measuring devices available. Feet are sometimes referred to as linear feet, which are simply the measurement of length in feet.

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.
