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. Micrometers (µm) measure cells (human cell = ~10–30 µm), bacteria (1–5 µm), and microelectronics. Pollen grains are ~15–100 µm wide.
To convert between Kilometer (km) and Micrometer (µm), use the following formulas:
1 Kilometer (km) = 1000000000 Micrometer (µm)
1 Micrometer (µm) = 9.999999999999999e-10 Kilometer (km)
0.5 km = 0.5 * 1000000000 µm = 500000000 µm
3 km = 3 * 1000000000 µm = 3000000000 µm
7 km = 7 * 1000000000 µm = 7000000000 µm
45 km = 45 * 1000000000 µm = 45000000000 µm
89 km = 89 * 1000000000 µm = 89000000000 µm
