How the conversion works

The relationship is in = nm × 3.937007874 × 10^-8. Both units measure length, so the conversion is a fixed factor that never changes. The figure is exact rather than approximate: since the international yard and pound agreement of 1959, an inch is defined as exactly 25.4 millimetres and a pound as exactly 0.45359237 kilograms, and every other imperial and US customary unit here is derived from those two.

Common questions

How many inches are in one nanometer?
One nanometer equals 3.937 × 10^-8 inches. in = nm × 3.937007874 × 10^-8.
How do you convert nanometers to inches?
Use in = nm × 3.937007874 × 10^-8. So 10 nm is 3.937 × 10^-7 in.
How many nanometers are in one inch?
One inch equals 25,400,000 nanometers, which is the reverse of the conversion above.
