30in is 762000 microns of vacuum
30 microns is about 0.001181102 inches.
0.030 mm
30um is 0.03mm
No!
There are 1000 microns in a millimetre. To convert micron to millimetre, you need to divide by 1000. 30/1000 leaves you with 0.03 millimetres.
Hectograms can't be converted to microns since they are not compatible to each other. Hectograms deals with mass while microns deals with length.Hence, there is no way to determine 30 hg in microns.
43 microns= 300gsm 1micron=Appx 7gsm[6.97gsm]
Above 5 microns, up to 30 microns
That could depend on several different factors, such as altitude etc... I do believe that at about sea level its -14.7 psi.

There are 76.2 cm to 30 inches.
30 inches = 76.2 centimeters
