## How to Convert Kilometers to Nanometers

Convert kilometers to nanometers with this simple formula:

Converting a kilometer length measurement to a nanometer measurement involves multiplying the length by the conversion ratio to find the result. One kilometer is equal to 1,000,000,000,000 nanometers, so to convert simply multiply 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.

Kilometers are a metric measurement and can be abbreviated as *km*, for example 1 km.
Nanometers are a metric measurement and can be abbreviated as *nm*, for example 1 nm.

A nanometer is an extremely small unit of length measurement, equal to one billionth of a meter. The nanometer
is used to measure things that are very small, such as the transistors and electrical pathways in computer processors
and nanotechnology. Internationally it is spelled *nanometre*.

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.
