How to perform key conversions involving length measurements

The formulas for conversion are represented below:

Kilometers to Millimeters Formula

m = km x 1000000


Example: 30 kilometers in meters:

mm = km x 1000000

mm = 30 x 1000000

mm = 30000000



Millimeters to Kilometers Formula

km = mm / 1000000


Example: 1500 meters in kilometers:

km = mm / 1000000

km = 1500 / 1000000

km = 0.0015



Frequently asked questions involving length and distance

3 km in millimeters

Considering that 1 kilometer equals 1000000 millimeters, you can use a rule of three to get that 3 km equals 3000000 millimeters.

  1 km - 1000000 mm

3 km - x

Apply the rule of three and get:

x km = 3000000 mkm2

x = 3000000 mm



10000 millimeters is equal to how many kilometers?

If every 1000000 millimeters we have 1 kilometer, just divide the number of millimeters (10000) by 1000000, so you will get that 10000 mm equals 0.01 km. Observe the calculation below:

km = mm / 1000000

Km = 10000 / 1000000

km = 0,01
