Formula
Centimeter to Nanometer conversion: 1 cm = 10000000 nm nanometers = centimeters × 10000000 1 nm = 1e-07 cm centimeters = nanometers × 1e-07
Example
Example: Convert 10 cm to nm: 10 cm × 10000000 = 100000000 nm So, 10 cm is about 100000000 nm. To convert back, multiply by 1e-07: 100000000 nm × 1e-07 = 10 cm.
