Picometers (pm) describe atomic radii and X-ray wavelengths. A hydrogen atom is ~53 pm wide. Used in crystallography and semiconductor engineering. The Kilometer (km) is used for longer distances like city-to-city travel (e.g., 50 km), marathon races (42.195 km), or highway spans (e.g., 100 km). It's also used in aviation and sports like cycling.
To convert between Picometer (pm) and Kilometer (km), use the following formulas:
1 Picometer (pm) = 1e-15 Kilometer (km)
1 Kilometer (km) = 1000000000000000 Picometer (pm)
100 pm = 100 * 1e-15 km = 1e-13 km
500 pm = 500 * 1e-15 km = 5e-13 km
1000 pm = 1000 * 1e-15 km = 1e-12 km
5000 pm = 5000 * 1e-15 km = 5.0000000000000005e-12 km
| Picometer (pm) | Kilometer (km) |
