Nano (symbol n) is a unit prefix meaning one billionth. Used primarily with the metric system, this prefix denotes a factor of 10 −9 or 0.000 000 001. It is frequently encountered in science and electronics for prefixing units of time and length. Examples. Three gold atoms lined up are about one nanometer (nm) long.

The prefixes of the metric system precede a basic unit of measure to indicate a decadic multiple and fraction of a unit. Each prefix has a unique symbol that is added to the beginning of the unit symbol. Some of the prefixes date back to the introduction of the metric system in the 1790s, but new prefixes have been added, and some have been ...

The IUPAC nomenclature of organic chemistry, for example, uses the numerical prefixes derived from Greek, except for the prefix for 9 (as mentioned) and the prefixes from 1 to 4 (meth-, eth-, prop-, and but-), which are not derived from words for numbers. These prefixes were invented by the IUPAC, deriving them from the pre-existing names for ...
Possibly an "Americana moment" similar to her 2017 look, she said – a bold pop of color, and surely a number appropriate to weather the D.C. cold. "This time around, she's not going to be a ...
Commonly, a decimal SI metric prefix (such as kilo-) is used with bit and byte to express larger sizes (kilobit, kilobyte). But, this is usually inaccurate since these prefixes are decimal, whereas binary hardware size is usually binary. Customarily, each metric prefix, 1000 n, is used to mean a close approximation of a binary multiple, 1024 n ...
