The formulas for conversion are represented below:
km = mm / 1000000
Example: 3000 Millimeters in Kilometers:
km = mm / 1000000
km = 3000 / 1000000
km = 0.003
mm = km * 1000000
Example: 2 Kilometers in Millimeters:
mm = km * 1000000
mm = 2 * 1000000
mm = 2000000
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
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
