## How to Convert Kilometers to Nanometers

To convert a kilometer measurement to a nanometer measurement, multiply the length by the conversion ratio. One kilometer is equal to 1,000,000,000,000 nanometers, so use this simple formula to convert:

The length in nanometers is equal to the kilometers multiplied by 1,000,000,000,000.

**For example,**here's how to convert 5 kilometers to nanometers using the formula above.

Kilometers and nanometers are both units used to measure length. Keep reading to learn more about each unit of measure.

## Kilometers

One kilometer is equal to 1,000 meters, which are defined as the distance light travels in a vacuum in a ^{1}/_{299,792,458} second time interval.

The kilometer, or kilometre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "kilo" is the prefix for 10^{3}. Kilometers can be abbreviated as *km*, for example 1 kilometer can be written as 1 km.

## Nanometers

One nanometer is equal to one-billionth (1/1,000,000,000) of a meter, which is defined as the distance light travels in a vacuum in a ^{1}/_{299,792,458} second time interval.

The nanometer, or nanometre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "nano" is the prefix for 10^{-9}. Nanometers can be abbreviated as *nm*, for example 1 nanometer can be written as 1 nm.

The nanometer is an extremely small unit of length measurement, often used to measure things that are very small, such as the transistors and electrical pathways in computer processors and nanotechnology.

We recommend using a ruler or tape measure for measuring length, which can be found at a local retailer or home center. Rulers are available in imperial, metric, or combination with both values, so make sure you get the correct type for your needs.

If you need a ruler you can also download and print our free printable rulers, which include both imperial and metric measurements.
