# 89 millimeters in decimeters

## Conversion

89 millimeters is equivalent to 0.89 decimeters.[1]

## Conversion formula How to convert 89 millimeters to decimeters?

We know (by definition) that: $1\mathrm{mm}=0.01\mathrm{dm}$

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

$1 ⁢ mm 89 ⁢ mm = 0.01 ⁢ dm x ⁢ dm$

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

$x\mathrm{dm}=\frac{89\mathrm{mm}}{1\mathrm{mm}}*0.01\mathrm{dm}\to x\mathrm{dm}=0.89\mathrm{dm}$

Conclusion: $89 ⁢ mm = 0.89 ⁢ dm$

## Conversion in the opposite direction

The inverse of the conversion factor is that 1 decimeter is equal to 1.12359550561798 times 89 millimeters.

It can also be expressed as: 89 millimeters is equal to $\frac{1}{\mathrm{1.12359550561798}}$ decimeters.

## Approximation

An approximate numerical result would be: eighty-nine millimeters is about zero decimeters, or alternatively, a decimeter is about one point one two times eighty-nine millimeters.
