### What is a Millimeter?

The **Millimetre** (international spelling; SI unit symbol mm) or millimeter (American spelling) is a unit of length in the metric system, equal to one-thousandth of a meter, which is the SI base unit of length. Therefore, there are one thousand millimeters in a meter and ten millimeters in a centimeter.

### What is a Nanometer?

The **nanometre** (SI symbol: nm) or nanometer (American spelling) is a unit of length in the metric system, equal to one billionth (short scale) of a meter (0.000000001 m).

The nanometre is often used to express dimensions on an atomic scale: the diameter of a helium atom, for example, is about 0.06 nm, and that of a ribosome is about 20 nm. The nanometre is also commonly used to specify the wavelength of electromagnetic radiation near the visible part of the spectrum: visible light ranges from around 400 to 700 nm.

### How to Convert Millimeter to Nanometers?

To convert Millimeter to Nanometers, simply multiply the Millimeter value by 1000000.

The formula used to calculate Millimeter to Nanometers -

**d**_{(mm)} = **d**_{(nm)} * 1000000

The distance *d* in Nanometers (nm) is equal to the distance *d* in Millimeters (mm) multiplied by 1000000.

### How many Nanometers in a Millimeter

In simple terms, 1 mm is equal to 1000000 nm.

The formula used is 1*1000000 = 1000000(nm)

### How many Millimeters in a Nanometer

1 Nanometer is equal to 1e-06 Millimeters. So we can also say that there are 1e-06 Millimeters in a Nanometer.
