1 km =_________cm

The metric system is widely used for scientific and everyday measurements. In this system, units are based on powers of 10, making conversions simple. When it comes to distance, 1 kilometer (1 km) is equal to 1000 meters (m). Now, to convert kilometers into centimeters (cm), we need to recall that:

• 1 meter = 100 centimeters
• 1 kilometer = 1000 meters

So, to convert 1 km into centimeters, we multiply the number of meters in 1 km (which is 1000 meters) by the number of centimeters in 1 meter (which is 100 cm). The calculation looks like this:

1 km = 1000 meters × 100 centimeters/meter = 100,000 centimeters

Therefore, 1 kilometer (1 km) is equal to 100,000 centimeters (or 10⁵ cm). This simple conversion rule holds true for any distance measured in kilometers. You can apply the same logic to convert any other value of kilometers to centimeters as well.
