To convert millimeters to kilometers, multiply the value by 1 × 10⁻⁶. To go the other way, multiply kilometers by 1,000,000 to get millimeters.
| Millimeters (mm) | Kilometers (km) |
|---|---|
| 1 mm | 1 × 10⁻⁶ km |
| 5 mm | 5 × 10⁻⁶ km |
| 10 mm | 1 × 10⁻⁵ km |
| 25 mm | 2.5 × 10⁻⁵ km |
| 50 mm | 5 × 10⁻⁵ km |
| 100 mm | 0.0001 km |
| 250 mm | 0.00025 km |
| 500 mm | 0.0005 km |
| 1,000 mm | 0.001 km |
| 2,500 mm | 0.0025 km |
| 5,000 mm | 0.005 km |
| 10,000 mm | 0.01 km |
| 100,000 mm | 0.1 km |
| 1,000,000 mm | 1 km |
Millimeter (mm). A millimeter is one thousandth of a meter, used for small measurements such as thickness and rainfall.
Kilometer (km). A kilometer is 1,000 meters and the standard unit for road distances in most countries, including India.
There are 1 × 10⁻⁶ kilometers in one millimeter.
Multiply the number of millimeters by 1 × 10⁻⁶. For example, 10 millimeters equal 1 × 10⁻⁵ kilometers.
One kilometer equals 1,000,000 millimeters.
0.001 kilometers. Other common values: 100 millimeters = 0.0001 kilometers and 10,000 millimeters = 0.01 kilometers.
