- The nanometre or nanometer is a unit of length in the metric system, equal to one billionth of a metre. One nanometre can be expressed in scientific notation as 1×10−9 m, in engineering notation as 1 E−9 m, and as simply 1/1000000000 metres.

The nanometre (international spelling as used by the International Bureau of Weights and Measures; SI symbol: nm) or nanometer ( American spelling) is a unit of length in the metric system, equal to one billionth ( short scale) of a metre ( 0.000 000 001 m ). One nanometre can be expressed in scientific notation as 1 × 10−9 m, and as 1. 1 ...

The nanometre (symbol: nm) is a unit used to measure length in the metric system. It is equal to one billionth of a metre ( 1 m / 1,000,000,000 ). The name combines the SI prefix nano- (from the Ancient Greek νάνος, nanos, "dwarf") with the parent unit name metre (from Greek μέτρον, metrοn, "unit of measurement").

hellonanometers are cool —Preceding unsigned comment added by 188.8.131.52 (talk) 20:36, 30 April 2009 (UTC) Unfortunately, the definition is incorrect because of the different definitions of a billion in American (10^9) and British (10^12) English. A nanometer is a billionth of a meter but a milliardth of a metre. I hope someone can fix this. Sim...
On Picometre there's a diagam of a helium atom which gives an idea of perspective. Any suggestions for a similar type of diagram in this article? 184.108.40.206 10:12, 9 June 2007 (UTC)
I do not like all the English spellings taking predominance over the US spellings. Far more scientists, semiconductor manufacturers and users of small measurements are in the US. Any objections to changing these pages to predominant US spellings, redirecting from the British spellings? --220.127.116.11 01:35, 26 September 2007 (UTC) 1. Yes. ~~Lazyg...
A friend of mine sent me an email last summer about nanotechnology -etc. He included this explanation:If the distance between New York and Los Angeles was a 'meter' then at this scale: 1. A human cell is about the size of a basketball court 2. Nanotechnology deals with objects smaller then a basketball 3. A nanometer is the size of an ant —Precedin...

The nanometre was formerly known as the millimicrometre – or, more commonly, the millimicron for short – since it is 1/1000 of a micron (micrometre), and was often denoted by the symbol mµ or (more rarely and confusingly, since it logically should refer to a millionthof a micron) as µµ.
The name combines the SI prefix nano- (from the Ancient Greek νάνος, nanos, "dwarf") with the parent unit name metre (from Greek μέτρον, metrοn, "unit of measurement"). When used as a prefix for something other than a unit of measure (as in "nanoscience"), nano refers to nanotechnology, or phenomena typically occurring on a scale of nanometres (see...
The nanometre is often used to express dimensions on an atomic scale: the diameter of a helium atom, for example, is about 0.06 nm, and that of a ribosome is about 20 nm. The nanometre is also commonly used to specify the wavelength of electromagnetic radiation near the visible part of the spectrum: visible light ranges from around 400 to 700 nm. T...
