How to Convert Kilometers to Nanometers

Tape measures can be used to measure units of length, and a calculator can be used to convert to another unit

Convert kilometers to nanometers with this simple formula:

nanometers = kilometers × 1,000,000,000,000

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.
5 km = (5 × 1,000,000,000,000) = 5,000,000,000,000 nm

Kilometers and nanometers are both units used to measure length. Learn more about length and find more length measurement conversion calculators. 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. Learn more about the metric system, including the common unit prefixes and how to convert between metric units.

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.
