Convert Nanometers to Feet
1 nanometer is 3.28e-9 ft. One nanometer is exactly 3.28083989501e-9 feet.
One nanometer is 3.2808 × 10^-9 feet. To convert nanometers to feet, multiply by 3.2808 × 10^-9; to go the other way, divide by 3.2808 × 10^-9 or multiply by 304800000. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and it follows from NIST. A billionth of a meter.

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: nanometres to feet 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 nanometers to feet? The converter and the working
- 1.Take the measurement in nanometers.
- 2.Multiply by 3.2808 × 10^-9 — that is how many feet fit in one nanometer.
- 3.To go back the other way, divide by 3.2808 × 10^-9, or multiply by 304800000.
Worked example: 25 nanometers to feet
- Formula
- nm × 3.2808 × 10^-9 = ft
- Arithmetic
- 25 × 3.2808 × 10^-9 = 8.20e-8 ft
- Answer
- 25 nm = 8.20e-8 ft
The factor is rounded for display; the figure above is computed from the full value.

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.
What is a foot?
Twelve inches, or exactly 0.3048 meters. Still the working unit of US construction.
How many feet are in a nanometer?
One nanometer is 3.2808 × 10^-9 feet. Going the other way, one foot is 304800000 nanometers. 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.

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 nanometer.
