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

Convert from kilometers to nanometers with this simple formula:
nanometers = kilometers × 1000000000000

1 Kilometer = 1,000,000,000,000 Nanometers

Learn How to Convert Kilometers to Nanometers Using our Conversion Formula

Converting a kilometer length measurement to a nanometer measurement involves multiplying your length by the conversion ratio to find the result. A kilometer is equal to 1000000000000 nanometers, so to convert simply multiply by 1000000000000.

For example, 5km = (5 × 1000000000000) = 5,000,000,000,000nm.

Kilometers and nanometers are both units used to measure length. Learn more about length and find more length measurement conversion calculators. A kilometer is a metric measurement and can be abbreviated as km, for example 1km. A nanometer is a metric measurement and can be abbreviated as nm, for example 1nm. 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.
