Conversion formula

The conversion factor from liters to deciliters is 10, which means that 1 liter is equal to 10 deciliters:

1 L = 10 dL

To convert 0.4 liters into deciliters we have to multiply 0.4 by the conversion factor in order to get the volume amount from liters to deciliters. We can also form a simple proportion to calculate the result:

1 L → 10 dL

0.4 L → V_(dL)

Solve the above proportion to obtain the volume V in deciliters:

V_(dL) = 0.4 L × 10 dL

V_(dL) = 4 dL

The final result is:

0.4 L → 4 dL

We conclude that 0.4 liters is equivalent to 4 deciliters:

0.4 liters = 4 deciliters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 deciliter is equal to 0.25 × 0.4 liters.

Another way is saying that 0.4 liters is equal to 1 ÷ 0.25 deciliters.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that zero point four liters is approximately four deciliters:

0.4 L ≅ 4 dL

An alternative is also that one deciliter is approximately zero point two five times zero point four liters.
