With this calculator, you can convert a distance entered in kilometers to millimeters. When entering a value, the calculator will display its equivalent in millimeters and meters+millimeters.

Below you can find additional information about using the calculator. In addition, you will also be able to learn about the relationship between kilometers and millimeters. Finally, you will find a conversion table.

## How to use the calculator to convert from kilometers to millimeters?

Step 1: Enter a distance or length in kilometers in the first input box.

Step 2: Its equivalent in millimeters will be displayed on the right-hand side panel.

Step 3: Its equivalent in meters+millimeters and the process used to convert to millimeters will be shown at the bottom.

## How many millimeters are there in a kilometer?

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

Kilometers and millimeters are units of distance or length in the metric system. We use the abbreviation km to represent kilometers and the abbreviation mm to represent millimeters.

In the metric system, the meter is the base unit of distance. The other units are derived from the meter using suffixes. In this case, milli means 10-3, so 1 millimeter equals 0.001 meters.

Also, kilo means 103, so 1 kilometer is equal to 1000 meters. Therefore, between millimeters and kilometers, the difference is 106, so 1 kilometer is equal to 1,000,000 millimeters.

## How to convert kilometers to millimeters?

Since 1 kilometer is equal to 1,000,000 millimeters, we can multiply the number of kilometers by 1,000,000 to get the number of millimeters. We can represent this in the following formula:

#### Example 1:

Determine the number of millimeters that are equal to 3 km.

Multiplying kilometers by 1,000,000, we get:

d(mm) = 3 × 1000000

d(mm) = 3000 000 mm

#### Example 2:

How many millimeters are equal to 3.466 kilometers?

Multiplying kilometers by 1,000,000, we get:

d(mm) = 3.466 × 1000 000

d(mm) = 3466000 mm

#### Example 3:

Determine the equivalence in millimeters of 17.234 kilometers.

By multiplying the given distance by 1,000,000, we have:

d(mm) = 17.234 × 1000000

d(mm) = 17234000 mm
