Nanometers to Miles (nm to mi)

1 nanometer equals 6.213711922×10⁻¹³ miles (rounded).

1 nanometer = 6.213711922×10⁻¹³ miles

How to convert nanometers to miles

To convert nanometers to miles, multiply the number of nanometers by 6.213711922×10⁻¹³. The factor is rounded to 10 significant digits. To go the other way, multiply miles by 1,609,344,000,000.

miles = nanometers × 6.213711922×10⁻¹³

Example: 10 nanometers = 6.213711922×10⁻¹² miles.

About these units

Nanometer (nm)

Metric (SI)Current unit

One billionth of a meter. Used for the wavelength of light (visible light is about 400–700 nm) and for chip feature sizes.

Greek for dwarf gave nano- its name, and the nanometer was once called something clumsier: the millimicrometre, or more often the millimicron, written mμ, since it is a thousandth of a micrometer. The prefix nano- was among those officially adopted when SI prefixes were first introduced in 1960, and the nanometer grew into the standard unit for optics and microelectronics. It sits a factor of ten above the older ångström, which is 0.1 nm and is still used for atomic distances.

Visible light spans roughly 400 to 700 nm, which is why color and spectroscopy are quoted this way. A helium atom is about 0.06 nm across and a ribosome about 20 nm. Chip makers have used nanometers since the late 1980s in names for manufacturing generations such as 32 nm and 22 nm. Those are labels for successive generations in the industry roadmap, and they describe typical feature sizes rather than one exact measurement. Readers should also beware that nm is sometimes written informally for the nautical mile.

1 nanometer = 1×10⁻⁹ meters (exactly).

Mile (mi)

US & ImperialCurrent unit

5,280 feet or 1,760 yards, exactly 1,609.344 meters. This is the statute (international) mile used on US and UK roads.

A thousand paces gave the mile its name. It descends from the Latin mille passus, the Roman mile, by way of Old English mil and Middle English myle. For centuries after Rome, miles of many lengths coexisted; a sixteenth-century Mercator map, for example, shows small, medium and large Flemish miles on a single scale bar. The English statute mile was fixed by an Act of Parliament under Elizabeth I in 1593, which declared that a mile contains eight furlongs, or 5,280 feet.

The 1959 international yard and pound agreement made that mile exactly 1,609.344 meters. A slightly longer US survey mile, about 1,609.347 meters, lingered in American land surveys and was slated for retirement from 1 January 2023. Today the mile is the road unit of the United Kingdom, the United States, Liberia and Myanmar, along with several territories such as the Bahamas, Belize, Guam and the US Virgin Islands. In Canada it survives chiefly in rail transport and horse racing.

1 mile = 1,609.344 meters (exactly).
