4 deciliters in liters

Conversion

4 deciliters is equivalent to 0.4 liters.^[1]

We know (by definition) that: $1 dl \approx 0.1 liter$

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

\frac{1 dl}{4 dl} \approx \frac{0.1 liter}{x liter}

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

x liter \approx \frac{4 dl}{1 dl} * 0.1 liter \to x liter \approx 0.4 liter

Conclusion: $4 dl \approx 0.4 liter$

The inverse of the conversion factor is that 1 liter is equal to 2.5 times 4 deciliters.

It can also be expressed as: 4 deciliters is equal to $\frac{1}{2.5}$ liters.

An approximate numerical result would be: four deciliters is about zero liters, or alternatively, a liter is about zero times four deciliters.
