Millionth of meter But not up to atomic level down where Size defines the properties


How big is a nanometer?

A nanometer (nm) is 1,000 times smaller than a micrometer. It is equal to 1/1,000,000,000th or one-billionth of a meter. Atoms are smaller than the naometer. One atom measure 0.1nm-0.3nm depending upon the element. For visualising the things at nanoscale,  Let us suppose you are shrinking a tenth of micron, width of human hair, approximately … Continue reading How big is a nanometer?
