Conversion formula
How to convert 665 kilometers to decimeters?

We know (by definition) that: 1 km = 10000 dm.

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

1 km / 665 km = 10000 dm / x dm

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

x dm = (665 km / 1 km) * 10000 dm x dm = 6650000 dm

Conclusion:
