Conversion formula
How to convert 81 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 / 81 m = 10 dm / x dm

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

x dm = (81 m / 1 m) * 10 dm → x dm = 810 dm

Conclusion:

81 m = 810 dm
