Conversion formula
How to convert 487 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 / 487 km = 10000 dm / x dm
Now, we cross multiply to solve for our unknown x:
x dm = (487 km / 1 km) * 10000 dm → x dm = 4870000 dm
Conclusion:
487 km = 4870000 dm
