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 640 liters into cubic meters we have to multiply 640 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

640 L → V_(m3)

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

V_(m3) = 640 L × 0.001 m3

V_(m3) = 0.64 m3

The final result is:

640 L → 0.64 m3

We conclude that 640 liters is equivalent to 0.64 cubic meters:

640 liters = 0.64 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 1.5625 × 640 liters.

Another way is saying that 640 liters is equal to 1 ÷ 1.5625 cubic meters.

Approximate result

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

640 L ≅ 0.64 m3

An alternative is also that one cubic meter is approximately one point five six three times six hundred forty liters.
