Conversion formula
How to convert 166 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 / 166 mm = 0.01 dm / x dm

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

x dm = (166 mm / 1 mm) * 0.01 dm → x dm = 1.6600000000000001 dm

Conclusion:

166 mm = 1.6600000000000001 dm
