Meters to Kilometers
Convert meters to kilometers with a calculator and a lookup table. The ratio is 0.001, so 1 m = 0.001 km; examples and the reverse direction included.

Formula for converting meters into kilometers
The unit table behind the converter relates meters and kilometers through one ratio, and that ratio works out to 0.001. In other words, 1 m = 0.001 km.
If an amount is already in kilometers, divide it by 0.001 to get meters; one kilometer is 1,000 meters.
Common meters-to-kilometers values
This lookup list shows 12 m values and what they become in km. The step from one row to the next is not constant, but the ratio of 0.001 between the columns is.
| Meters (m) | Kilometers (km) |
|---|---|
| 20 | 0.02 |
| 40 | 0.04 |
| 80 | 0.08 |
| 150 | 0.15 |
| 300 | 0.3 |
| 600 | 0.6 |
| 1,200 | 1.2 |
| 3,000 | 3 |
| 6,000 | 6 |
| 12,000 | 12 |
| 40,000 | 40 |
| 80,000 | 80 |
The converter formats numbers the same way, which means the km column above is what you would see after typing the m value into the widget.
Step by step: m to km
Convert 85,000 m first. Using 0.001 as the multiplier, the answer displayed is 85 km.
Next, 9,500 m: the converter shows 9.5 km. Because the ratio is fixed, the km figure is 0.001 times the m figure.
For the last case, begin with 0.012 kilometers. Multiplying by 1,000 gives 12 meters.
Reverse direction (km to m)
If the amount you have is in kilometers, go to Kilometers to Meters. Here 1 km = 1,000 m, and the layout mirrors this page.
Any other pairing is available in the Length Converter, built on the same conversion function as this page.

Frequently asked questions
One meter equals how many kilometers?
Each meter corresponds to 0.001 kilometers, which means 0.01 kilometers for 10 meters and 0.1 kilometers for 100 meters.
How many meters are in one kilometer?
1 km = 1,000 m. The reverse ratio is the reciprocal of 0.001, so 10 km comes to 10,000 m.
170,000 meters equals how many kilometers?
Multiply 170,000 by 0.001 and the answer is 170 km.
Will the km figure be rounded?
Calculation uses ordinary floating-point numbers, then the display is trimmed: 10 significant digits for values from 1 to 1,000, 8 for values below 1, and up to 6 decimals above 1,000. For this pair, 0.123456789 m gives 0.00012345679 km and 1,234.5678 m gives 1.2345678 km.
What calculation sits behind m to km?
The unit table gives meters and kilometers each a multiplier against a common reference unit. Dividing one multiplier by the other leaves 0.001, which is applied to whatever number is entered.
How do I convert kilometers back to meters?
The page titled "Kilometers to Meters" covers it, or you can press the swap button in the widget above. For this direction multiply by 1,000, or equivalently divide by 0.001. As a check, 25 km comes to 25,000 m.
