About the units

Nautical mile (nmi)

Exactly 1,852 m, originally one minute of latitude. Nautical miles are used in aviation and at sea, together with the knot (one nautical mile per hour).

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).

Frequently asked questions

How many nanometers are in one nautical mile?

There are 1,852,000,000,000 nanometers in one nautical mile, and this value is exact by definition.

How do I convert nautical miles to nanometers?

Multiply the number of nautical miles by 1,852,000,000,000. For example, 10 nmi × 1,852,000,000,000 = 18,520,000,000,000 nm.

How many nautical miles are in one nanometer?

One nanometer equals 5.399568035×10⁻¹³ nautical miles. That is the reverse factor, 1 ÷ 1,852,000,000,000.

What is 10 nautical miles in nanometers?

10 nmi = 18,520,000,000,000 nm.
