Conversion formula
How to convert 66 millimeters to decimeters?

We know (by definition) that: 1 mm = 0.01 dm.

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

1 mm / 66 mm = 0.01 dm / x dm

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

x dm = (66 mm / 1 mm) * 0.01 dm → x dm = 0.66 dm

Conclusion:

66 mm = 0.66 dm
