## How to Convert Nanometers to Kilometers

To convert a measurement in nanometers to a measurement in kilometers, divide the length by the following conversion ratio: 1,000,000,000,000 nanometers/kilometer.

Since one kilometer is equal to 1,000,000,000,000 nanometers, you can use this simple formula to convert:

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

**For example,**here's how to convert 5,000,000,000,000 nanometers to kilometers using the formula above.

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

## What is a Nanometer?

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 billionths, or 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.

## What is a Kilometer?

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.^{[1]} One kilometer is equal to 0.621371 miles.

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 thousands, or 10^{3}. Kilometers can be abbreviated as *km*; for example, 1 kilometer can be written as 1 km.

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 a combination of both values, so make sure you get the correct type for your needs.

Need a ruler? Try our free downloadable and printable rulers, which include both imperial and metric measurements.
