How to perform key conversions involving length measurements

The formulas for conversion are represented below:

Millimeters to Kilometers Formula

km = mm / 1000000


Example: 3000 Millimeters in Kilometers:

km = mm / 1000000

km = 3000 / 1000000

km = 0.003



Kilometers to Millimeters Formula

mm = km * 1000000


Example: 2 Kilometers in Millimeters:

mm = km * 1000000

mm = 2 * 1000000

mm = 2000000



Frequently asked questions involving length and distance

100 Millimeters are equal to how many Kilometers

Considering that 1 Millimeter is equivalent to 0.000001 Kilometer, you can use a rule of three to obtain that 100 Millimeter equals 0.0001 Kilometer.

    1 mm - 0.000001 km

100 mm - x

Apply the rule of three and get:

x mm = 0.0001 kmmm

x = 0.0001 km



100 Kilometers is equal to how many Millimeters?

If every 1 Kilometers we have 1000000 Millimeters, just multiply the number of Kilometers (100) by 1000000, so you will obtain that 100 km equals 100,000,000 mm. Observe the calculation below:

mm = km * 1000000

mm = 100 * 1000000

mm = 100,000,000
