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. Picometers (pm) describe atomic radii and X-ray wavelengths. A hydrogen atom is ~53 pm wide. Used in crystallography and semiconductor engineering.
To convert between Kilometer (km) and Picometer (pm), use the following formulas:
1 Kilometer (km) = 1000000000000000 Picometer (pm)
1 Picometer (pm) = 1e-15 Kilometer (km)
0.5 km = 0.5 * 1000000000000000 pm = 500000000000000 pm
3 km = 3 * 1000000000000000 pm = 3000000000000000 pm
7 km = 7 * 1000000000000000 pm = 7000000000000000 pm
45 km = 45 * 1000000000000000 pm = 45000000000000000 pm
89 km = 89 * 1000000000000000 pm = 89000000000000000 pm
