Convert 5km to milimetre
The correct answer and explanation is:
To convert kilometers to millimeters, follow these steps:
- Start by converting kilometers to meters. Since 1 kilometer is equal to 1,000 meters, multiply the number of kilometers by 1,000. For example, 5 kilometers is equivalent to 5,000 meters.
- Next, convert meters to millimeters. There are 1,000 millimeters in 1 meter. So, multiply the number of meters by 1,000. In this case, 5,000 meters is equal to 5,000,000 millimeters.
Therefore, 5 kilometers equals 5,000,000 millimeters.
Explanation:
The metric system operates on powers of 10, which makes conversions relatively straightforward. Each unit is 10 times greater or smaller than the next one. For example, 1 kilometer (km) is 1,000 meters (m), and 1 meter is 1,000 millimeters (mm). This relationship is the key to converting between the units.
- Kilometer to meter: Multiply by 1,000 (because 1 kilometer = 1,000 meters).
- Meter to millimeter: Multiply by 1,000 again (because 1 meter = 1,000 millimeters).
By following these conversion steps, you can quickly and easily convert kilometers to millimeters. In summary:
5 km × 1,000 (to convert to meters) = 5,000 meters
5,000 meters × 1,000 (to convert to millimeters) = 5,000,000 millimeters
Thus, 5 kilometers is equal to 5,000,000 millimeters.
