To convert kilometers to other units of length, you need to use the conversion factors. Here are the conversions:
1 kilometer = 1,000 meters
1 kilometer = 100,000 centimeters
1 kilometer = 1,000,000 millimeters
To convert kilometers to meters, you multiply the number of kilometers by the conversion factor of 1,000.
To convert kilometers to centimeters, you multiply the number of kilometers by the conversion factor of 100,000.
To convert kilometers to millimeters, you multiply the number of kilometers by the conversion factor of 1,000,000.
For example, if you want to convert 2 kilometers to meters:
2 kilometers * 1,000 meters/kilometer = 2,000 meters
Similarly, you can use the respective conversion factors to convert kilometers to centimeters and millimeters.
