Kilometers to Nanometers Conversion
Enter the length in kilometers below to get the value converted to nanometers.
How to Convert Kilometers to Nanometers
To convert a kilometer measurement to a nanometer measurement, multiply the length by the conversion ratio.
Since one kilometer is equal to 1,000,000,000,000 nanometers, you can use this simple formula to convert:
The length in nanometers is equal to the kilometers multiplied by 1,000,000,000,000.
How Many Nanometers Are in a Kilometer?
There are 1,000,000,000,000 nanometers in a kilometer, which is why we use this value in the formula above.
1 km = 1,000,000,000,000 nm
Kilometers and nanometers are both units used to measure length. Keep reading to learn more about each unit of measure.
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 103. Kilometers can be abbreviated as km; for example, 1 kilometer can be written as 1 km.
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.
