How to convert 428 kilometers to meters?

We know (by definition) that: $1 km = 1000 m$

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

\frac{1 km}{428 km} = \frac{1000 m}{x m}

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

x m = \frac{428 km}{1 km} * 1000 m \to x m = 428000 m

Conclusion: $428 km = 428000 m$

428 kilometers is equivalent to 428000 meters
