# How Do I Convert NM To Centimeters?

The length of a dollar bill is 15.5956 cm. If the radius of a gold atom is .1442nm, how many gold atoms could lie side by side along the length of a dollar bill. First, we must multiply .1442 x 2=diameter.2884nm radius. But where do I go from there????

1 meter = 1,000,000,000 nanometers.

1 x 10 to the negative ninth power since 1 nanometer = 1,000,000,000

A nanometer is a meter times 10 to the -9 power. A centimeter is a meter times 10 to the -2 power. So the difference is a factor of 10 to the 7th power. To convert, take the number of centimeters and multiply by 10 to the 7th power (10^7). Example, 1 cm would equal 1 cm X 10^7 or 1 x 10^7 Nanometers, which is 10,000,000 nm.

A centimeter is .... Of a meter

Nm=10^-9 (.000000001) Cm=10^-2 (.01)
(10^-9)-(10^-2) or (.000000001)-(.01)
=1cm=10^-7nm

The nm could be nanometer as well as nautical mile. 1 nanometer is equal to 1e-7 cms. And 1 nautical mile is equal to 185,200 cms.
