Conversion formula
How to convert 64 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 / 64 mm = 0.01 dm / x dm

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

x dm = (64 mm / 1 mm) * 0.01 dm → x dm = 0.64 dm

Conclusion:

64 mm = 0.64 dm

Conversion in the opposite direction

The inverse of the conversion factor is that 1 decimeter is equal to 1.5625 times 64 millimeters.

It can also be expressed as: 64 millimeters is equal to 1 / 1.5625 decimeters.

Approximation

An approximate numerical result would be: sixty-four millimeters is about zero decimeters, or alternatively, a decimeter is about one point five six times sixty-four millimeters.
