Conversion formula

The conversion factor from liters to cubic meters is 0.001, which means that 1 liter is equal to 0.001 cubic meters:

1 L = 0.001 m3

To convert 18 liters into cubic meters we have to multiply 18 by the conversion factor in order to get the volume amount from liters to cubic meters. We can also form a simple proportion to calculate the result:

1 L → 0.001 m3

18 L → V_(m3)

Solve the above proportion to obtain the volume V in cubic meters:

V_(m3) = 18 L × 0.001 m3

V_(m3) = 0.018 m3

The final result is:

18 L → 0.018 m3

We conclude that 18 liters is equivalent to 0.018 cubic meters:

18 liters = 0.018 cubic meters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 cubic meter is equal to 55.555555555556 × 18 liters.

Another way is saying that 18 liters is equal to 1 ÷ 55.555555555556 cubic meters.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that eighteen liters is approximately zero point zero one eight cubic meters:

18 L ≅ 0.018 m3

An alternative is also that one cubic meter is approximately fifty-five point five five six times eighteen liters.
