How to convert 4 meters to kilometers?

We know (by definition) that: 1 m = 0.001 km.

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

1 m / 4 m = 0.001 km / x km

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

x km = (4 m / 1 m) * 0.001 km → x km = 0.004 km

Conclusion:

4 m = 0.004 km

Conversion in the opposite direction
