The normal units are Pascals below standard atmospheric pressure. However, extremely high quality vacuums are sometimes measured in terms of the number particles per unit volume. Very specialised equipment can create vacuum of one trillionths of atmospheric pressure, or 10 nanoPascals. This is equivalent to around 100 particles per cubic centimetre. However, in outer space, it can go down to only a handful of hydrogen atoms (not even molecules) per cubic metre.
