How to Convert Kilometers to Nanometers
Converting kilometers (km) to nanometers (nm) is a simple conversion within the metric system. One kilometer is equal to 1,000,000,000,000 nanometers.
Formula
Nanometers = Kilometers × 10^12
or
nm = km × 10^12
Step-by-step process
- Take the measurement in kilometers
- Multiply that number by 10^12
- The result is the equivalent amount in nanometers
Examples
- 1 kilometer = 1,000,000,000,000 nanometers
- 0.000001 kilometers = 1,000,000 nanometers
- 0.000000001 kilometers = 1,000 nanometers
When to Convert Kilometers to Nanometers
This conversion is crucial in fields like nanotechnology, quantum physics, and semiconductor manufacturing, where measurements are often at the atomic or molecular scale.
Common Kilometers to Nanometers Conversions
Here is a table of common kilometer to nanometer conversions for quick reference:
| Kilometers (km) | Nanometers (nm) | Kilometers (km) | Nanometers (nm) |
|---|---|---|---|
| 1 | 1.000E+12 | 0.000001 | 1,000,000 |
| 0.1 | 1.000E+11 | 0.0000001 | 100,000 |
| 0.000000001 | 1,000 | 0.0000000001 | 100 |
Frequently Asked Questions
How many nanometers are in a kilometer?
There are exactly 1,000,000,000,000 nanometers in one kilometer.
Why is the conversion factor 10^12?
The metric system is based on powers of 10. A kilometer is 1000 meters, and a meter is 1,000,000,000 nanometers, so 1000 * 1,000,000,000 = 10^12.
