3 meters in decimeters

Conversion formula
How to convert 3 meters to decimeters?

We know (by definition) that: $1\mathrm{m}=10\mathrm{dm}$

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

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

Conclusion: 3 ⁢ m = 30 ⁢ dm

Conversion in the opposite direction

The inverse of the conversion factor is that 1 decimeter is equal to 0.0333333333333333 times 3 meters.

It can also be expressed as: 3 meters is equal to $\frac{1}{\mathrm{0.0333333333333333}}$ decimeters.

Approximation

An approximate numerical result would be: three meters is about zero decimeters, or alternatively, a decimeter is about zero point zero three times three meters.
