      Relation Between Millimeter (mm) and Nanometer (nm)

      Let me explain to you about the relation between Millimeter mm and Nanometer (nm) first before moving to the conversion process. Because it’s essential to grasp what these units represent.

      What is Millimeter (mm)?

      A millimeter is a unit of length equal to 10−3 meters. Millimeter (mm) is a unit of length measurement which is commonly used in Nanoengineering. Part of the metric system, ideal for small-scale precision measurements. Common in engineering, construction, and manufacturing..

      What is Nanometer (nm)?

      Millimeter (mm) is another unit of length measurement that is used in Astronomy. A nanometer is a unit of length equal to 10−9 meters.. Part of the metric system, ideal for small-scale precision measurements. Common in engineering, construction, and manufacturing..

      How to Convert Nanometer (nm)?

      The conversion between Millimeter (mm) and Nanometer (nm) follows a simple formula:

      Millimeter = Millimeter × 1000000

      Where, 1000000 is the value that allows you to convert between Millimeter (mm) and Nanometer (nm).

      So,

      1 Nanometer = 1000000 Millimeter

      And, 1 Millimeter = 1/1000000 Nanometer

      Examples of Converting Millimeter (mm) to Nanometer (nm)

      To convert any value from Millimeter (mm) to Nanometer (nm), simply multiply the amount of Millimeter (mm) by the conversion factor:

      1 Nanometer = 1000000 Millimeter

      For example, if you want to convert 5 Millimeter into Nanometer and the conversion factor is 1000000, then:

      5 Millimeter = 5 x 1000000 Nanometer
