## Nanometer and Meter

The nanometer and the meter are units of length in the International System of Units (SI). They are used to describe distances or sizes at different scales.

### The meter

A meter (symbol: m) is the basic unit of length in the SI. It is defined as the distance that light travels in a vacuum in 1/299,792,458 of a second. The meter is often used to measure human scale objects and distances, such as the height of a person or the length of a room.

### The nanometer

A nanometer (symbol: nm) is an SI unit of length, equal to one billionth of a meter (1 nm = 1 x 10^-9 m). The nanometer is mainly used in physics, chemistry, biology, and engineering to measure extremely small structures. For example, a single water molecule is about 0.28 nanometer in diameter, and a single silicon atom is about 0.11 nanometer in diameter.

### Converting between meter and nanometer

The relationship between these two units is simple: 1 meter is equal to 1,000,000,000 nanometers. Therefore, to convert meters to nanometers, you multiply the number of meters by 1,000,000,000.

`1 meter = 1,000,000,000 nanometers`

To convert nanometers to meters, divide the number of nanometers by 1,000,000,000. This makes the conversion between these units simple and straightforward.

`1 meter = 0.000000001 nanometer`
