Formula
Nanometer to Millimeter conversion: 1 nm = 1e-06 mm millimeters = nanometers × 1e-06 1 mm = 1000000 nm nanometers = millimeters × 1000000
Example
Example: Convert 10 nm to mm: 10 nm × 1e-06 = 1e-05 mm So, 10 nm is about 1e-05 mm. To convert back, multiply by 1000000: 1e-05 mm × 1000000 = 10 nm.
