Conversion formula
How to convert 409 meters to decimeters?

We know (by definition) that: 1 m = 10 dm.

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

1 m / 409 m = 10 dm / x dm

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

x dm = (409 m / 1 m) * 10 dm → x dm = 4090 dm

Conclusion:

409 m = 4090 dm
