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. The Millimeter (mm) is perfect for very small measurements like the thickness of a credit card (0.76 mm), the diameter of a pencil lead (0.5-0.7 mm), or the size of small hardware components. Commonly used in engineering, jewelry design and manufacturing.
To convert between Kilometer (km) and Millimeter (mm), use the following formulas:
1 Kilometer (km) = 1000000 Millimeter (mm)
1 Millimeter (mm) = 0.000001 Kilometer (km)
0.5 km = 0.5 * 1000000 mm = 500000 mm
3 km = 3 * 1000000 mm = 3000000 mm
7 km = 7 * 1000000 mm = 7000000 mm
45 km = 45 * 1000000 mm = 45000000 mm
89 km = 89 * 1000000 mm = 89000000 mm
