Conversion formula

The conversion factor from milliliters to liters is 0.001, which means that 1 milliliter is equal to 0.001 liters:

1 ml = 0.001 L

To convert 40 milliliters into liters we have to multiply 40 by the conversion factor in order to get the volume amount from milliliters to liters. We can also form a simple proportion to calculate the result:

1 ml → 0.001 L

40 ml → V_(L)

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

V_(L) = 40 ml × 0.001 L

V_(L) = 0.04 L

The final result is:

40 ml → 0.04 L

We conclude that 40 milliliters is equivalent to 0.04 liters:

40 milliliters = 0.04 liters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 liter is equal to 25 × 40 milliliters.

Another way is saying that 40 milliliters is equal to 1 ÷ 25 liters.

Approximate result

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

40 ml ≅ 0.04 L

An alternative is also that one liter is approximately twenty-five times forty milliliters.
