Millimeters to Kilometers Calculator








With this calculator, you can find the equivalent in kilometers of a distance entered in millimeters. When entering the distance, the number of kilometers will be displayed immediately.

Below you can find additional information about using the calculator. Also, you can learn about the relationship between millimeters and kilometers and how to transform between these units.

How to use the calculator from millimeters to kilometers?

Step 1: The distance in millimeters must be entered in the first input box β€œMillimeters”. Any valid distance can be entered.

Step 2: The number of kilometers will be displayed on the right panel.

Step 3: The distance in kilometers + meters and the process used to convert to kilometers will be displayed at the bottom.

How many millimeters are there in a kilometer?

1 kilometer contains 1 000 000 millimeters, one million millimeters. Alternatively, 1 millimeter is equal to 0.000001 kilometers.

Millimeters and kilometers are units of distance or length in the metric system. In this system, the meter is the base unit for measuring distance, so all other units are derived from the meter.

Distinctive suffixes are used to name units derived from the meter. In this case, milli means 10-3, so we multiply the distance in millimeters by 0.001 to get the distance in meters. And kilo means 103, so we multiply the distance in kilometers by 1000 to get meters.

Therefore, between millimeters and kilometers, there is a difference of 106, that is, 6 digits.

How to transform from millimeters to kilometers?

Since 1 kilometer is equal to 1,000,000 millimeters, we need to divide the distance in millimeters by 1,000,000 to get the distance in kilometers. Therefore, we find a distance d in kilometers (km) by dividing the given distance d in millimeters by 1,000,000.

d(km) = d(mm)/1000000

Example 1:

How many kilometers are equal to 2,000,000 mm?

To get the distance in kilometers, we divide by 1,000,000:

d(km) = 2000000/1000000

d(km) = 2 km

Example 2:

Convert 550000000 millimeters to kilometers.

We divide by 1,000,000 to find the number of kilometers:

d(km) = 550000000/1000000

d(km) = 550 km

Example 3:

Convert 5000 millimeters to kilometers.

If we divide the millimeters by 1,000,000, we have:

d(km) = 5000/1000000

d(km) = 0.005 km
