Measuring the Microscopic World
A nanometer (nm) is a unit of length in the metric system equal to one billionth of a meter. It is often used to measure the size of objects at the atomic and molecular level. For example, the diameter of a DNA molecule is about 2 nm, and the thickness of a human hair is about 100,000 nm.
Converting Nanometers to Kilometers
To convert nanometers to kilometers, we need to divide the number of nanometers by 1,000,000,000. For example, to convert 1 nm to kilometers, we would divide 1 by 1,000,000,000, which gives us 0.000000001 km.
Table of Nanometer to Kilometer Conversions
The following table shows the conversion of nanometers to kilometers for various values:
| Nanometers (nm) | Kilometers (km) |
|---|---|
| 1 | 0.000000001 |
| 10 | 0.00000001 |
| 100 | 0.0000001 |
| 1,000 | 0.000001 |
| 10,000 | 0.00001 |
| 100,000 | 0.0001 |
| 1,000,000 | 0.001 |
| 10,000,000 | 0.01 |
| 100,000,000 | 0.1 |
| 1,000,000,000 | 1 |
