The depletion of ozone layer is measured in PPM. Here PPM is called as Parts Per Million.
The two terms ppm and ml are not similar measures. PPM (parts per million) is a ratio and can apply to mass, volume, etc., while ml (milliliter) is a unit of volume - 1/1000 of a liter.
It can be measured by volume
Milk is measured by volume. It is not measured by weight.
1-3 ppm by volume
ppm by volume is "parts per million" by volume as opposed to ppm by weight. ppm by volume and ppm by weight are not the same thing It has been suggested that the drinking water in West Hampshire be adultery with 1 ppm by volume of fluoride. This is an example of ppm by volume
PPM or parts per million
Print speed is measured in pages per minute (ppm).
The depletion of ozone layer is measured in PPM. Here PPM is called as Parts Per Million.
Volume is measured in cubic units
Volume is measured in decibals.
A gallon of gasoline (roughly 4 kilograms) will produce about 10 kilograms of carbon dioxide. Since ppm are measured in volumes, this is equivalent to about 20 cubic meters of carbon dioxide at STP. As the "given volume of air" is not specified no definite answer can be given except that it is comparison of the available volume to the 20 cubic meters calculated above.

No. ppm is a ratio - a pure number - whereas a litre (not litter!) is a measure of volume, with dimensions [L3].
(ppm) parts per million. Hope this helps:)
0.05% by volume.
