How to convert 628 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.

\frac{1 m}{628 m} = \frac{0.001 km}{x km}

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

x km = \frac{628 m}{1 m} * 0.001 km \to x km = 0.628 km

Conclusion: $628 m = 0.628 km$

628 meters is equivalent to 0.628 kilometers
