Conversion formula

The conversion factor from liters to milliliters is 1000, which means that 1 liter is equal to 1000 milliliters:

1 L = 1000 ml

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

1 L → 1000 ml

0.4 L → V_(ml)

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

V_(ml) = 0.4 L × 1000 ml

V_(ml) = 400 ml

The final result is:

0.4 L → 400 ml

We conclude that 0.4 liters is equivalent to 400 milliliters:

0.4 liters = 400 milliliters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 milliliter is equal to 0.0025 × 0.4 liters.

Another way is saying that 0.4 liters is equal to 1 ÷ 0.0025 milliliters.

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 hundred milliliters:

0.4 L ≅ 400 ml

An alternative is also that one milliliter is approximately zero point zero zero three times zero point four liters.
