How to convert 5 decimeters to millimeters?

We know (by definition) that: 1 dm = 100 mm.

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

1 dm / 5 dm = 100 mm / x mm

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

x mm = (5 dm / 1 dm) * 100 mm → x mm = 500 mm

Conclusion:

5 dm = 500 mm
