About the units

Nanometer (nm)

One billionth of a metre. Visible light wavelengths run from about 380 to 750 nm, and semiconductor process nodes are named in nanometres. One nanometer equals 1×10⁻⁹ meters (m).

Inch (in)

A US customary and imperial unit defined as exactly 25.4 mm since 1959. Twelve inches make a foot. Screen sizes, tire diameters and lumber dimensions are usually given in inches. One inch equals 0.0254 meters (m).

Frequently asked questions

How many inches are in one nanometer?

There are 3.937007874×10⁻⁸ inches in one nanometer, and this value is exact by definition.

How do I convert nanometers to inches?

Multiply the number of nanometers by 3.937007874×10⁻⁸. For example, 10 nm × 3.937007874×10⁻⁸ = 3.937007874×10⁻⁷ in.

How many nanometers are in one inch?
