Conversion formula
How to convert 50 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 / 50 mm = 0.01 dm / x dm

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

x dm = (50 mm / 1 mm) * 0.01 dm → x dm = 0.5 dm

Conclusion:

50 mm = 0.5 dm

Conversion in the opposite direction

The inverse of the conversion factor is that 1 decimeter is equal to 2 times 50 millimeters.

It can also be expressed as: 50 millimeters is equal to 1 / 2 decimeters.

Approximation

An approximate numerical result would be: fifty millimeters is about zero decimeters, or alternatively, a decimeter is about zero times fifty millimeters.
