What are meters and kilometers?
The meter is the SI base unit of length, defined by the distance light travels in 1/299,792,458 of a second. A kilometer is 1,000 meters, the standard metric unit for road distances. 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 meters to kilometers
1 m = 0.001 km. To convert, multiply the number of meters by 0.001. For example, 5 m = 0.005 km, and 20 m = 0.02 km. To go the other way, multiply kilometers by 1,000 (since 1 km = 1,000 m).
