A nanometer is quite small a billionth of a meter.
a unit of spatial measurement that equals one billionth 10 9 of a meter the head of a pin is about 1 million nanometers across a human hair is about 60000 nanometers in diameter while a dna molecule is between 2 12 nanometers wide one billionth of a meter approximately the length of three to six atoms placed side by side or the width of a single strand of dna the thickness of a human hair is between 50000 and 100000 nanometers source a unit of measurement equal to one billionth of one meter one nanometer is 0 000000001 meter one millimeter is 0 001 meter count how many more zeros there are in one than in the other if there are six then the ratio is 1 with six zeros 1000000 that s a million answer because there are 10 9 nanometers in one meter and 10 2 centimeters in one meter there are 10 7 centimeters in one nanometer conversely there are 10 7 nan ometers in one a nanometer is quite small a billionth of a meter it is 20 times wider than the diameter of a hydrogen atom in terms of the electromagnetic spectrum 1 nanometer is about the wavelength of soft x rays hard x rays and gamma rays have a shorter wavelength the width of a dna double helix the molecule that carries our genetic code is about 2 nanometers a nanometer nm is 1000 times smaller than a micrometer it is equal to 1 1000000 000th or one billionth of a meter when things are this small you can t see them with your eyes or a light microscope objects this small require a special tool called a scanning probe microscope a meter is a little bit bigger than a yard a lot of things in our everyday lives are around the same size as a meter an elementary school student is approximately one meter m tall however most professional basketball players are at least 2 meters m tall shaquille o neill at 7 1 is 2 1 m tall notice that a centimeter is 1 100 th of a meter that also means that a meter is 100 times as big as a centimeter if an object were a meter wide it would also be 1000000000 nanometers wide so something that is only 1 nm wide is very small indeed  one nanometer corresponds to a length which is one billionth of a meter or about one ten thousandth the diameter of a human hair source one billionth of a meter 1 1000000000 source a nanometer is a billionth of a meter 10 9 m and around 50000 times finer than the average human hair source a nanometer is a measure of length 1 nm 0 000000001 meter 1 billionth of a meter one billionth of a meter approximately the length of three to six atoms placed side by side or the width of a single strand of dna the thickness of a human hair is between 50000 and 100000 nanometers source a unit of measurement equal to one billionth of one meter trying to understand just how small the nanoscale is can be very difficult for people a nanometer is a unit of measurement for length just as you have with meters and centimeters a nanometer is one billionth of a meter 0 000000001 or 10 9 meters the word nano comes from the greek word for dwarf the term nanoscale is used to refer to objects with dimensions on the order of 1 100 nanometers nm to understand how small a nanometer is we typically compare the nanoscale to objects that we know how big or small they are nanotechnology q how big is a nanometer a a nanometer is a millionth of a millimeter or about 10 hydrogen atoms long transistors are being made as small as 22 nanometers by comparison an average human hair is about 100000 nanometers wide here are some other everyday objects measured in nanometers one inch equals 25 4 million nanometers a sheet of paper is about 100000 nanometers thick a human hair measures roughly 50000 to 100000 nanometers in diameter a meter is a little bit bigger than a yard a lot of things in our everyday lives are around the same size as a meter an elementary school student is approximately one meter m tall however most professional basketball players are at least 2 meters m tall shaquille o neill at 7 1 is 2 1 m tall
