About this conversion

The kilometer (km) is a unit of length in the metric (SI), commonly used for road and highway distances and geographic measurements. The um (um) belongs to the a different measurement system and is typically found in measurements related to various applications. By definition, one kilometer is one thousand meters. The conversion factor between these two units is 1000000000: multiplying any value in km by this number gives the equivalent in um. For example, 10 km equals 10000000000.0000 um. Going the other direction, 1 um equals 0 km. Adopted alongside the metric system, the kilometer became the standard unit for land distance in most countries by the 20th century.
