Conversion formula
How to convert 2 kilometers to millimeters?

We know (by definition) that: 1 km = 1000000 mm.

We can set up a proportion to solve for the number of millimeters.

1 km / 2 km = 1000000 mm / x mm

Now, we cross multiply to solve for our unknown x:

x mm = (2 km / 1 km) * 1000000 mm → x mm = 2000000 mm

Conclusion:

2 km = 2000000 mm

The inverse of the conversion factor is that 1 millimeter is equal to 5e-07 times 2 kilometers.

It can also be expressed as: 2 kilometers is equal to 1 / 5e-07 millimeters.

Approximation

An approximate numerical result would be: two kilometers is about two million millimeters, or alternatively, a millimeter is about zero times two kilometers.
