what is a nano?

Answer 1

it's a factor of 10^-9

Answer 2

'Nano' is also gaining ground as a futuristic slang term for 'nanotechnology' and/or 'nanomachines' in SF stories. See Greg Bear's 'Queen of Angels' for good examples of this use. In a typical scene, a character facing danger takes from her cosmetics bag a small cold-cream pot containing pearlescent grey grease. This is nano - billions of microscopic, pre-programmed machines. She drops various items into the goo - a lighter, some salt, keys, screws and washers found in the room. These are absorbed into the grease. After an hour, a fully functional automatic pistol begins to emerge from the goo...

Look up nano- in
Wiktionary, the free dictionary.Nano- is a prefix (symbol n) in the SI system of units denoting a factor of 10−9. It is often used in prefixing time and length units encountered in electronics and computer systems, like 30 nanoseconds (symbol ns) and 100 nanometres (nm). It was confirmed in 1960 and comes from the Greek νᾶνος, meaning dwarf.

Answer 4

a nano is one billonth of a second. Term is usually used in electronics for timing.

Answer 5

A nano has no independent existence of its own; the term 'nano' is a prefix & means 'one billionth'. Thus, a nanosecond is one thousandth of a microsecond, one millionth of a millisecond, one billionth of a second.

Unless of course you are talking about an i-Pod Nano, so called because it is so tiny.

Answer 6

a nano- is a thousandth of a micro-

hence a nanosecond (10^-9 sec) is a thousand time shorter than a microsecond (10^-6 sec)

See the wiki page

Answer 7

a nano is one billonth of a second. 11.8 inchs if I remember right. The distance light travels in 1/1,000,000,000. of a second
