## Millimeters to nanometers conversion factor and formulas

Formula

The conversion factor between millimeters and nanometers is 1,000,000. This represents the ratio of nanometers per one millimeter. To calculate the value in nanometers, we can either multiply by the conversion factor or divide by its inverse.

### Multiplication

To convert from millimeters to nanometers, multiply millimeters by 1,000,000.
The formula is expressed as:
mm × 1,000,000 = nm

### Division

Alternatively we can divide by the inverse conversion factor to get the same result.
The inverse of 1,000,000 is 1/1,000,000 or 0. To convert from millimeters to nanometers, divide millimeters by 0.
The formula is expressed as:
mm ÷ 0 = nm

A conversion from millimeters to nanometers are units within in the metric (SI) or SI compatible systems.

SI Unit

Within the SI (metric) system of measurement, the millimeter is officially defined as one thousandth (1/1,000) of a meter. It is commonly used when measuring very short lengths. Internationally it is spelled 'millimetre' whereas the U.S. spells it 'millimeter'. The symbol for millimeters is mm.

SI Unit

A nanometer is a metric (SI) measure of length defined as one billionth (1/1,000,000,000) of a meter or a millionth (1/1,000,000) of a millimeter. The nanometer is frequently used for measurement of integrated circuitry in the computer semiconductor industry. The symbol for nanometer (or nanometre) is nm.
