This converter allows you to convert kilometers [km] to nanometers [nm] or nanometers [nm] to kilometers [km]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.
Convert kilometers to nanometers
There are two simple ways to convert kilometers [km] to nanometers [nm]. In the first calculation method, the value in kilometers [km] is divided by 10-12. The second method multiplies the value in kilometers [km] by 1012.
- Nanometers [nm] = kilometers [km] ÷ 10-12
- Nanometers [nm] = kilometers [km] * 1012
Convert nanometers to kilometers
Converting nanometers [nm] to kilometers [km] is easy and can be done in two ways. The first method involves multiplication, whereby the value in nanometers [nm] is multiplied by 10-12. The second variant is a division. Here, the value in nanometers [nm] is divided by 1012.
- Kilometers [km] = nanometers [nm] * 10-12
- Kilometers [km] = nanometers [nm] ÷ 1012

Speed
While mph is used in the USA, km/h is the standard in Europe, and seafaring and aviation rely on knots. This speed converter is the perfect tool for accurately converting between various units of speed.
