This converter allows you to convert millimeters [mm] to nanometers [nm] or nanometers [nm] to millimeters [mm]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.

1 millimeter [mm] = 1,000,000 nanometers [nm]1 nanometer [nm] = 10-6 millimeters [mm]

Convert millimeters to nanometers

There are two simple ways to convert millimeters [mm] to nanometers [nm]. In the first calculation method, the value in millimeters [mm] is divided by 10-6. The second method multiplies the value in millimeters [mm] by 1,000,000.

  • Nanometers [nm] = millimeters [mm] ÷ 10-6
  • Nanometers [nm] = millimeters [mm] * 1,000,000

Convert nanometers to millimeters

Converting nanometers [nm] to millimeters [mm] is easy and can be done in two ways. The first method involves multiplication, whereby the value in nanometers [nm] is multiplied by 10-6. The second variant is a division. Here, the value in nanometers [nm] is divided by 1,000,000.

  • Millimeters [mm] = nanometers [nm] * 10-6
  • Millimeters [mm] = nanometers [nm] ÷ 1,000,000

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.
