Convert Feet to Nanometers
1 foot is 304,800,000 nm. One foot is exactly 304800000 nanometers.
One foot is 304800000 nanometers. To convert feet to nanometers, multiply by 304800000; to go the other way, divide by 304800000 or multiply by 3.2808 × 10^-9. The factor is exact rather than rounded: it follows from NIST. Twelve inches, or exactly 0.3048 meters.

Factors are entered by hand from NIST rather than derived from a units library, so the ones that terminate are exact rather than rounded.
The same converter answers this pair however it is written: feet to nanometres is the British spelling of the same units — the metre and the litre are spelled that way outside the United States and the quantity does not change.
How do you convert feet to nanometers? The converter and the working
- 1.Take the measurement in feet.
- 2.Multiply by 304800000 — that is how many nanometers fit in one foot.
- 3.To go back the other way, divide by 304800000, or multiply by 3.2808 × 10^-9.
Worked example: 25 feet to nanometers
- Formula
- ft × 304800000 = nm
- Arithmetic
- 25 × 304800000 = 7,620,000,000 nm
- Answer
- 25 ft = 7,620,000,000 nm
The factor is exact, so this figure is exact too — only the display is rounded.

What is a foot?
Twelve inches, or exactly 0.3048 meters. Still the working unit of US construction.
What is a nanometer?
A billionth of a meter. Visible light runs from about 380 to 750 nm, and a semiconductor process node is named after one even though it stopped describing a physical dimension years ago.
How many nanometers are in a foot?
One foot is 304800000 nanometers, exactly. Going the other way, one nanometer is 3.2808 × 10^-9 feet. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
Every length unit here
The whole group — 13 units with their symbols and the size of each one in meters — is on the conversion index, along with every pair it makes. The table above already gives each of them relative to a foot.
