Convert from millimeter to nanometer formula

Total nanometer = Total millimeter x 1000000

For example, if you want to convert 25 Millimeter to Nanometer then,

25 mm = 25 x 1000000 = 25000000 nm

A millimeter is the smallest unit. There are 10 mm in one centimeter, if an object is smaller than one centimeter, you would use millimeters. A scientist measuring something under a magnifying glass might use millimeters to represent a tiny specimen.


A nanometer (also "nanometre") is a unit of measurement used to measure length. One nanometer is one billionth of a meter, so nanometers are certainly not used to measure long distances. Instead, they serve to measure extremely small objects, such as atomic structures or transistors found in modern CPUs.
