You can't directly convert between volume and length. It's like asking how many apples equal a banana - they are different kinds of things!
To make a comparison, you need to know the shape of the container that holds the milliliters.
For example:
* A cubic meter (m³) is a volume that is equal to 1,000,000 milliliters (mL).
* But a meter-long line doesn't have a volume, so you can't say how many milliliters are in it.
