How Do You Convert Nanometers to Millimeters?

A millimeter is a unit of length that equals one-thousandth of a meter. A nanometer is also a unit of length, but it is equal to one-millionth of a millimeter.

  1. Take the appropriate measurements

    First, measure exactly how many nanometers you need to calculate into millimeters.

  2. Run the calculations

    Get a calculator or a pen and paper and begin processing the calculations. Take the number of nanometers, then divide them by 1,000,000 (x/1,000,000 = y) to get the number of millimeters. To convert to nanometers, take the millimeter amount and multiple by 1,000,000 to get the number of nanometers (y*1,000,000 = x).

  3. Double-check your work

    Run the calculations again to be sure that your work is accurate and precise.
