How many meters are there in one kilometer?

One kilometer is equivalent to 1000 meters because the metric system is based on powers of ten, which allows for easy conversions within the system. The prefix "kilo-" in the metric system denotes a factor of 1000. Therefore, when converting kilometers to meters, you multiply the number of kilometers by 1000. This fundamental relationship is a cornerstone of understanding major metric conversions, making it essential knowledge for various applications in math, science, and engineering.
