What are kilometers and meters?
A kilometer is 1,000 meters, the standard metric unit for road distances. The meter is the SI base unit of length, defined by the distance light travels in 1/299,792,458 of a second. For scale: a doorway is about 2 m (6.6 ft) tall, and a marathon is 42.2 km (26.2 mi).
How to convert kilometers to meters
1 km = 1,000 m. To convert, multiply the number of kilometers by 1,000. For example, 5 km = 5,000 m, and 20 km = 20,000 m. To go the other way, multiply meters by 0.001 (since 1 m = 0.001 km).
